Unable to withdraw

I met Qian Li on my Facebook and the Messenger. Then, we change to Line for a chat. After a month, he introduces me to open an MT5 account at IFS MARKETS to trade gold. I must pay him a 2.5% commission. I changed four brokers in three weeks: IFS MARKETS DingHui international Locus market BKYHYO. I found that these brokers sound bad and do not do well, decided to withdraw. They promised to withdraw the money within three to five days, but after five days, I went to their Skype customer service and found that I had been blocked, even Line, Messenger, and email were blocked. Since there is no way to contact the company, of course there is no way to get a dime. I still have $89,309 USDT in my last broker, BKYHYO. This is pure financial fraud.
