MEX rejected withdrawal without reason

MEX rejected withdrawal without reason. My account No. 33508416 opened an account through their Dubai office in September. I wanted to invest in October. It has been a month since I withdrew the money from the platform. The funds have not been processed yet. The official website asked the customer service to inform the cash department to hurry up. But it has never been processed. It's too hateful and shameless. Why could I deposit but not withdraw?
