Freelancer.com — 2000$ were stolen and account was closed without reason and explanation.

I worked with Freelancer.com over 2 years, had 60 reviews, all 5-stars, 100% of my orders were completed successfully and every my customer was highly satisfied — I provided good service and everything was fine. Then war started, I lived in Russia, so I moved to South East Asia 6 months ago and living in Vietnam now. I had 2000$ in my freelancer.com account, but when I tried to withdraw it in my new Vietnamese bank, they limited my account, asked some documents for verification, I sent documents, they didn't respond over a week and then just closed my account without any explanation. I didn't violate any rules, I just moved to another country. I'm kind of shocked by being scammed after two years of good work there.
