I have seen a lot of people who got their account blocked because of AML and other issues.
If your account of CEX got blocked and you can't fix that issue, RisoLab are always there to help you.
We have helped unlockung more than $5Million this year so far.

Really? So you are selling an account unlock service for CEX? It's pretty unrealistic for newbies to account for advertising CEX unlock service. Do you have a website? How do we believe you have helped unlock CEX accounts? Sounds like you want to scam OP again by calling through Telegram. OP, be careful when you are dealing on Telegram; most are scammers there.
About your allegations, it doesn't seem like a scam. They want to make sure the account is in the right hands. Try to explain to them about your issues very well and properly. Write to their social media as well. I faced locking issues with Binance but later solved them. I tried to reach their social media when I hadn't got any solution from their support. Finally, they enabled my withdrawal, though the account is still locked.
