Deposit succesfully, but the plaform occupied the fund

After I successfully deposited the funds, I never got my money. I asked the customer service and it says say to make up for the loss. I made it clear that I didn’t need to make up for any loss. The platform said at the beginning that it would be refunded and then change to not refund it with a poor attitude. Pretending to be formal platform to scam investors' money.
