WITHDRAW PROBLEM

I only worked with this company for a short period of time, like 1 week, and then they told me that I had made a mistake and I would not receive my profit. They then told me that I could only get the money I deposited and that if I agreed, I should sign the document they sent me. I accepted this and signed the document. However, they have not refunded me my principal money for more than a month and I cannot get an answer from either e-mail or WhatsApp support lines. And I'm still waiting to get my money back from this company. Before sending this document to us, they kept us waiting for more than a month to withdraw money. And in our last conversation, the company's WhatsApp support line said that it would send us our money faster if we made a withdrawal by typing the TRC20 address in the bank transfer section. Afterwards, I did not receive a response to any of my messages and I have been waiting for my money to arrive for 1 month.
