I think you're just getting the short end of the stick here. There are a couple of verification sites/exchanges where it takes me 2-3 tries for my ID to get accepted, even though it's me just taking the photo again (for example Binance, Localbitcoins and Kraken) all had these issues for me, for some reason.

It's understandable that they would request you to send funds to your old addresses or use your old IP addresses since it's a safety precaution but it's very confusing why you weren't allowed to withdraw after verifying your ID.

Good luck OP, hope it get's fixed - don't think it's an exit scam, just them being weird.
