Yeah, that's really funny. Because they didn't have that rule before my order. I have video of all their rules, so it was added recently. Most likely today.
Record:
https://streamable.com/atjf5vCan you check if your coins are still at the deposit address from the order, or if the exchanger sent them on?
If they are 'dirty' coins as they claim, they should not move them.
Otherwise, if I understood correctly, OP sent USDT. Perhaps this could be a case of requiring Tether to freeze these tokens, as there is little chance that the OP will get their money back through the goodwill of a go-go.exchange.
This is the wallet I sent the coins to.
