Unable to withdraw money

I opened an account on this platform in March this year and deposited $3,000 for trading. During the period, if the account slippage is serious, apply for withdrawal. When I opened the account, the customer service repeatedly guaranteed that the withdrawal would take one to three working days, but it had been a week since I had withdrawn the funds, and the account still hadn’t arrived. During this period, I consulted the customer service on the official website every time with a few mechanical sentences, without any substantive suggestions. Emails don't get a reply either. WeChat customer service even blocked friends, suspected of running away. Hope to severely punish the rubbish black platform
