I recommended this exchange to a friend. He made a mistake and indicated USDC instead of USDT in the request. As a result, the exchange successfully transferred 30 euros, but it's unclear where exactly. When I asked about it, they replied, "be more careful." Now I don't understand where my money is. Where did it go if the wallet is invalid and not from this network—it's unclear. I definitely won't be coming back here next time.
