If a deposit is not made in the correct way again in the future, we will no longer process it

I transferred 500 USDT to the designated wallet using the platform's deposit method, but the platform refused to credit my deposit, claiming it had not received the funds. The chain status query shows that the transfer was successful, and the platform wallet address can add networks and receive funds normally. Yet it now keeps asking me to make the deposit again, always using the reason that it has not received the funds. The funds I have already transferred are also hard-earned money, but now it refuses to resolve the loss..
