I deposited USD 5,000 into D Prime. After suffering trading losses, my account was left with USD 3,588. I then applied for a withdrawal, but they refused to process it. My account manager sent me a message saying that my account had violated the trading rules and asked me to sign an agreement. I signed the agreement, but they still did not return my principal.

I signed the agreement on July 8, and now it is almost September, but the funds still have not arrived. I contacted customer service, and they also said they would urge the account manager to follow up, but the account manager still has not responded.

I contacted the platform, and they told me to contact my account manager. However, the account manager has not responded for a long time. During this period, I also tried to make withdrawals, but every time I submitted a withdrawal request, I was told that my account was abnormal and that I needed to contact my account manager.

However, every time I contacted the account manager, he told me that there was no problem on his side and that I should wait for confirmation from the risk-control team.

At this point, I really do not know who I should contact to resolve this matter.
