Account was maliciously emptied

There should be 8,400 USD in my account. After I withdrew 1,200 USD, it was under review until exposure. They suddenly lifted my blockade and contacted me about the issue of withdrawal. I received it on the same day. They emptied the 7,200 USD in my account that night when I did not withdraw it at all, as shown in the picture. The last time I withdrew was 1,200 USD, and then the balance of my account was deducted 7,200 USD with a system withdrawal. If it was my own withdrawal, it would have been transferred to the account by local bank transfer. Actually I did not send the withdrawal application and did not receive the money.
