Options when improperly expelled from Schengen [closed]

Currently in Spain but ordered to leave. Reviewing an application which included photocopy of passport, someone found my entry stamp from a year ago, but failed to find the entrance stamp into U.K. within the ninety days (would have been 89 were it not for bus delays). I have other evidence beside the exit stamp (ATM records). Sent a letter to the hotel denying the application and ordering me out of Spain. Doesn't say out of Schengen, and last I heard, Schengen countries don't share data on entries and exits. But if I don't leave on my own and get "escorted" out, not only do I lose some flexibiity in where, I also get a police record, which is shared.

Someone asked for an image, but I don't see how to upload it. Putting it somewhere that identifies me is not going to happen. Downvote my paranoia if you wish. I read Spanish so I know what thye letter says.

It allows two months for appeal, but the appeal has to be done here, and the removal order is fifteen days. A local lawyer will appeal for free, but he's not available until eight days after I received the letter, fifteen days after it was written.

So I'm trying to figure out what to do if the appeal goes too slowly.

Ironically, I applied for NIE because multiple bankers said you can't open an account without it, and multiple realtors said you can't buy or rent without a bank account and an NIE. Other expats said the same things. But the day I got the letter, I signed a contract with neither at another realtor's office, and the next day a different banker said using a passport number instead of an NIE is fine.

Andorra has agreed to not admit anyone inadmissible to Spain. Monaco is part of Schengen. But it seems that I would be safe in Gibraltar, San Marino, or Vatican. Anyone here know a reason why that's not the case?
