Deposit Not Credited Despite Completed Status

I am experiencing a serious issue with my OKX account, where my balance has not been updated after a successful crypto deposit. My user ID on the platform is 593***. I transferred 850 USDT via the Tron (TRC20) network to the address TY5x47d3VEtjUfTd22HZc3GbkCFiQwL9m. The transfer status is shown as “Completed” and the Transaction ID is e72aB...F3d9c. The blockchain confirms that the transaction was successfully processed, yet my OKX account balance still shows zero and the deposit has not been credited. Despite the transaction being visible and confirmed on the Tron blockchain, my funds are not appearing in my OKX account, which is causing me financial concern and preventing me from using my money on time. I reached out to OKX live support about this problem, but I only received automated replies instead of a proper manual investigation. Support did not check the transaction on the network or provide any concrete explanation for why the funds are missing from my balance. I request that OKX immediately conduct a detailed manual verification of this TRC20 deposit, identify the 850 USDT linked to my account ID and promptly credit the full amount to my account. I also expect a clear written explanation of the cause of this issue and confirmation once the 850 USDT has been correctly reflected in my OKX balance.
