They suspended my membership and reset my balance

Hello, while I was trading with gold in Forex and I was in a profit position in my account, they suddenly deleted the credit and sent me an e-mail, stating that I was abusing the negative balance protection. I closed my transactions and responded to their request. I do not think that I made any mistakes or mistakes. All my transactions were always in a profit position. There was no decrease in which I could use the bonus. Then they examined my account and 6 days later they sent me an e-mail saying that I had broken the rules. They reduced the balance in my account to 0 and closed my account. I asked them to provide me with evidence indicating which or where I made a mistake or abused it, but they did not.
