Report the scam platform fxdd

I traded in fxdd more than ten years ago, and I always thought that FXDD was a listed company and an experienced forex dealer. On February 16th, I deposited $302, $75 bonus, and earned $100. On May 16th I applied for a withdrawal of $415. The platform said that the amount exceed the limit and did not give me money. The $415 deducted in the account flew. I haven't seen a refund for half a month.
