My hotel "blocked" 5,000 dollars when I arrived and now is taking again the money

I'm going to disagree with the other answers here, and state that the hotel didn't follow the correct procedure for charging your card, which is what has caused your problem.

When you checked in, the hotel did an authorization for the $5,000. This is normal - it basically "reserves" the money so that it's there when they come to charge your card, which normally doesn't occur until you check-out.

As a part of that authorization is an auth code - presuming they gave you a copy of the receipt it should show that code on it, along with the fact that it was only a "pre-auth" or something to that effect.

When they actually come to charge your code, they are supposed to use that "auth code" to make the charge. This tells the bank that this charge is to be taken out of the money that has already been reserved. It sounds like this didn't happen in that case, so instead of placing a charge against the existing reserved $5,000, the bank treated it as a NEW, additional charge of $3,000.

Most likely the hotel made this "mistake" deliberately. If they had issued the charge against the auth code, then the remaining funds under that authorization would have been cleared. ie, the $5,000 authorization would have been removed, and replaced with the $3,000 charge. When they came to charge you the additional $2,000 they would have had to do that as a new charge, without a pre-authorization, and there is the possibility that it would have been rejected (eg, if you had taken the funds out of your account).

At this point the hotel only has $3,000 of your money - although technically if they wanted to they could charge an additional $5,000 to your card and it would be approved, on the grounds that they had already obtained a pre-authorization for that amount. (I'm not suggesting they would do that, just that they physically could).

When you to check-out and they attempt to charge the remaining $2,000, one of two things will happen. If they issue that charge using the pre-auth code obtained when they did the authorization, then the additional $2,000 will be taken from that amount, and the remaining $3,000 reservation will be returned to your account relatively quickly (possibly immediately, but normally within a day).

Alternatively if they issue the next $2,000 as a new charge (without the auth code) then they will take a further $2,000 from your account - and NOT release the pre-auth. At that point, depending on the timing, your bank account will be down $10,000 - although the hotel will only have $5,000 of that. Then, around a week after the initial authorization was done, the $5,000 that was reserved will be returned to you.

In the US banking system (I don't know if it differs in other countries) these are two separate types of transactions. Here's what I know from working for many years in the card services department of a bank.

When companies use the word "block", "reserve", "hold" or "authorization" they're referring to a type of transaction that is used to verify that funds are available and prevent them being spent for a short period of time. This is usually done in cases where there could be some variation in the actual amount due at the time of payment, such as at a hotel, gas station or rental car company. No money actually leaves your bank or is transferred into their account, but you will generally be unable to use the funds until the hold expires. Typically this would be about 3 business days, but could be longer or shorter depending on lot of complicated factors that influence how these authorizations are processed by your bank. There are also some companies whose software will continue to renew the hold until the time they're ready to make your final transaction. The authorization can sometimes be cancelled by the company that placed it, but it's not something that is done very commonly in most industries and you might have a hard time finding someone who knows how to remove it and has the authority to do so. I would hope that the employees at a hotel that deal with customer billing would be familiar with this process, but in my experience many of them are not. I would not be at all surprised to learn that there is significant variation in how long it takes these holds to expire if your bank is located in another country.

The other type of transaction is the actual charges to your account. This is the type of transaction you're used to encountering, where the amount due is known at the time of the transaction and funds leave your account and are electronically transferred to the receiver's bank almost immediately.

Unfortunately, because these two types of transactions are done separately and at different times, you can run into the type of situation you've described, where your funds are still being held because of the first authorization and have also been actually removed with a regular transaction, creating the impression that you've been charged twice. What can be done about it is often quite dependent on the banking software being used by the company that has placed the hold. The better programs automatically revoke and update (if necessary) the hold, while slightly less good ones sometimes allow the hotel staff to cancel the hold manually, but they may not do so unless you bring it to their attention. If nothing is done, the hold will eventually expire and your funds will be available to you again at that point.

As others have mentioned, this is something you are likely to encounter while traveling, so having more funds available than you will actually need is a good idea, as is presenting a credit card instead of a debit card at check-in so that you don't run into as many problems from having the hold on. Presenting a credit card doesn't stop the hotel from placing a hold on your funds but in many cases, you have a credit limit that exceeds the amount of money you actually intend to spend on your trip, and you'll still have access to the money you have in the bank for other purchases in the meantime. The fact that none of your actual money is tied up and the fact that the hold will eventually expire without causing any true charges to appear on your credit card bill can save you from the worst of the pain.

Some comments have pointed out that some policies conflict with this information, but unfortunately there tends to be quite a bit of variation in what you will actually encounter in the real world. It's a complicated process that involves interactions between several big companies and it's not always predictable how that will work out for you. Your best bet when you run into this kind of problem is to start with the hotel employees. If they know what they're doing and the hotel chain has good software, they may be able to release the hold or adjust the amount of the hold to account for what you've already paid right from the computer at the front desk. It sounds like you're not lucky enough to be dealing with one of these hotels though, so your next step is to speak with a supervisor about the situation. If the hotel is using particularly horrendous banking software, they might actually have to call the bank to have the hold released. At the bank where I worked, we could remove holds from customer accounts, but were strongly discouraged from doing so unless it was absolutely necessary and we could get the company that placed the hold to send us some kind of documentation to prove that they wanted it released (that usually meant speaking to both the customer and the hotel manager on the phone and then having the manager fax a signed letter to us requesting for the hold to be released). You might get some help from your bank directly, since policies differ from bank to bank, but most of them consider this to be a problem caused by the hotel and will send you back to them for help. It's far from a perfect process and I'm sorry you're running into trouble with it.

I just want to clarify what other answers have said. The hotel does not have $8000, notwithstanding what the card representative said. I base that on the "blocked" status you see online. What they have is a lockout on $5000 (which should be reduced to $2000) plus an actual $3000 transfer.

You need to speed up the "unblocking" of the $3000. Confirm that the hotel has released that. You may be able to call your bank and have them hurry that up.

If by some fluke the online statement is wrong and the hotel has received $8000, they should revert the extra immediately, and if they don't, notify your bank that there is a duplicate charge.

All answers are very good, I would like to also add something else to protect yourself in case you need to dispute the charges later. Get a clear receipt from the hotel with all charges. While this may not help you now, it will help you once you have left the hotel and you find an error was made and you can easily get your bank to correct the issue by disputing any incorrect charge.

This is pretty normal in my experience with Hire Car companies and I expect that Hotels do the exact same thing.

Upon arrival, they get a pre-approval or pre-authorisation for an amount expected to cover the eventual bill. With Hire Car companies, sometimes that is enough to cover the expected eventual bill AND the full insurance excess on your hire. That validates that your card has enough balance to cover the expense. This pre-authorisation is often not carried through and completed when finalizing the billing, often because the amount is indicative rather than final and the amount is usually released back onto your card after approximately three days, perhaps more depending on your banking/card provider and their merchant processor.

Then, when the bill is to be settled they process a charge on your card for the final amount or, for a sub-amount along the way if they are making incremental billing as in your case.

Do not worry, you are not out of pocket and the pre-authorisation will disappear from your account.
