I deposited more than 15,000 u on September 2, 2023, and participated in the exchange’s couple activities. I couldn't withdraw money that day. They said I needed to recharge 13140USDT. After the recharge was completed, I could withdraw the money. I completed the deposit on September 15th, and customer service said that the transaction volume needed to reach 10,000 USDT. I reached 15922USDT, but the withdrawal was unsuccessful. The customer service said that I needed to pay 20% personal income tax and asked me to recharge 10608 USDT. I don’t know what kind of requirements the customer service will ask after my recharge is completed. This is the HFM exchange website, https://sj.hfm66.net.im/vip/
