Customer service vanished after I paid the tax

To withdraw 200,000 USD, 12% of the personal income tax must be paid before the review and withdrawal process. The first time I paid the tax, I used two different names in two transactions. Then I was contacted by the customer service saying that taxes must be paid by the same name, so the second transaction of taxes was refunded to my trading account and I had to pay an additional 8001 USD. I hurriedly scraped together the money and paid it off. In the evening, the customer service said the interval between these two payments was too long to be reviewed by the system, and I must pay the tax again. I paid the tax again the next day, but the customer service said it would take 24 hours to review and unfreeze my account, but now the customer service has disappeared and unreachable.... This is a black-hearted broker that made me heavily in debt now.
