I can't withdraw money or cancel my contract.

When I requested a withdrawal for the first time, I was told to apply from the exchange app, so I did so. After about a day of not receiving the money, I contacted the person in charge, Mr. Tokushima, and was told that the money could not be withdrawn because it had not been a month since the account was opened. There was no explanation about this when I opened the account. I managed to negotiate and was able to transfer only 20 minutes of the amount I wanted to withdraw. I was told that it would take 10 business days for the next withdrawal, but I never heard of that! Two weeks later, I had no choice but to contact Mr. Tokushima to withdraw $40,000, and I applied through the exchange app around 9:30 in the morning. I did not receive the money and inquired several times, but there was no clear answer. In the evening, I was told that I would not be able to withdraw money unless I first paid the taxes on the account balance. Of course, this is completely new to me. If that's the case, why didn't you say so in the first place? The principal amount was 7.1 million dollars (approximately 47,000 dollars), but thanks to the guidance of a teacher, the balance exceeded 440,000 dollars. I was told that I would not be able to withdraw money unless I transferred about $88,000 in taxes on the balance. Since I only want to withdraw $40,000, I asked them to pay the tax from the balance in my account, but I can't! One point of tension. I asked them to just give me back the principal, as I would be giving up all profits, but that didn't work either. I talked to the person in charge about what to do, but all they told me was to pay the taxes first. I don't have $88,000. Please help me.
