Review Hacked account

My sportybet account is hacked some hours ago through and am debited from my bank gtb 33,200. Pls do something about this pls. I have been using this account for awhile now and I have not gotten any issues at all on the account not until recently when I tried to load my sportybet account with 500naira. I did that successfully. But few minutes later I begin to receive alert on my bank account debited all what I have there.
