1. The customer service of this website (fake okx Ouyi) asked me to upgrade my account for the first time and asked me to pay 30% of the account balance as the upgrade fee, and said that I would withdraw the money after the payment. 2. After paying 52844.4 USD back and forth, I was still not allowed to withdraw the funds. In the name of fraudulent money laundering, my account was frozen, and I was required to pay another 12% of the account balance to prove that my account was fine. I made a withdrawal. I paid 5026.71 USTD yesterday. The more I think about it, the more wrong I am.
