UK visit visa refused twice? How do I reach Embassy? [duplicate]

I'm a woman working in the UAE and I applied for a visit visa to see my friend in Aberdeen and also for tourism. I had booked my hotels and bought my tickets. I provided employment letter and bank statement with my application. I had mentioned I require almost £4,000 for my 13 day trip. I had provided a bank statement until end of October with closing amount of £4,600 and mentioned that my salary of November and December will be deposited before my travel date which was 24th of December.

But the first time it was refused, mentioning that I had only £3,550 as my closing amount. I went through my bank statement - this amount was for September first!! They had overlooked my saving after first of September. I discussed with many companies and I paid a lawyer for consultation. All came to the point that the officer made an error and overlooked my statement. I thought maybe adding more money to my bank statement would make it better. I asked my father for money and he provided me with £2,600 cash which I deposited it to my account.

In my second application I mentioned this was a gift from my father. I provided an invitation letter from my friend. My November salary was also deposited to my account. So my closing amount was now £8,400. But they refused it again!! They had provided one point only. Mentioning that I have added £2,600 and I didn't provide enough documentation for where I got the money. So because of this they cannot trust my documentation.

I had provided my original employment paper, original bank statement. All they had to do was to call the bank but they didn't. Simply with false accusation they refused my visa. All my documents were originals and I was ready for this trip. I had everything planned and it was supposed to be 13 days only. But I won't apply again. My tickets are reserved for 24th of December and I went through so much stress for this two time for a simple visit visa. I have been looking for a way to reach the Embassy. I know there is no right of appeal for a visit visa application.

But how can someone like me can prove their case?

I can apply for judicial review but by the time I get an answer, it is way past my travel date and my annual leave from my job has already finished. I wanted to know if there is any other way I can try. I have lost hope and I'll be cancelling my tickets and hotels soon. I just wanted to see if there is anything else I can do. The first two images are for the first refusal and the third is for my second refusal.
