Withdrawal is unavailable, with frequent renewals of the account

The platform offers no access to withdrawing money with different excuses. It also asked me to deposit a certification fee, which were transferred into my account directly, to make the bank statement meet the regulation. Besides, the bank statement were renewed everyday. When the application for withdrawing was approved, they remitted money to me. But they prevented me from withdrawing with another excuse. Then they transferred back to the account to make the bank statement meet the regulation.
