I opened an account and deposited funds into GMI through my relative's ID card, and the trading was profitable. However, in early October, I was unable to withdraw funds or trade. They requested a guarantee letter in order to withdraw funds, and I had to acknowledge that the trading was not compliant. My relative was very concerned about providing such information, which prevented me from providing the guarantee letter. They also requested that GMI deduct the profits and return my principal. In a spirit of friendly negotiation, I have been communicating and negotiating for a month, but the account manager has not replied to me, and the customer service is unable to handle it.
