unable to withdraw, keep on asking fees

Dear Sir or Madam, I started trading with Definitive Forex (formerly known as Vast Forex) on August of 2021 and I made a profit of $6333702 They required upfront tax payment 14.8% of 6,333,702 in order to withdraw my money of $6638318. So, I paid 937,791 USDT in taxes on December 23, 2021. After that, they I paid 47000 USDT for withdrawal fee on January 20,2022. Now, they are asking 23500 USDT fee in order to release the money to me. They can deduct 23500 USDT from profit and I don’t mind
