Restricted withdrawals

My account has been restricted from trading and withdrawals. They've been investigating and informed me to contact customer support. I answered their questions and submitted relevant proof. Nevertheless, they are saying the funds I acquired are suspected of being fraudulent. I merely bought this ETH from another person and had completely no concept the place the cash got here from. Their present answer is to refund these allegedly fraudulent funds, however I need to know who will compensate me for my losses? I'm additionally a sufferer; that is outrageous!
