Unable to withdraw

I deposited at Coin W in July 2021, the account was blocked when the transaction was withdrawn after trading for a month, and the online customer service was asked to first submit a series of certificates, and then ask you to wait patiently, pay attention to the mailbox and will inform you as soon as possible, etc. Liaring nonsense, it will make you wait until you wonder if life has been suspended at a certain moment, and it has been almost a year until today, and I have not recieved any information in the mailbox. I can only say that I was cheated. I deposited with a bank card twice, unsuccessful withdrawal once.
