Accounts and no service

My revolving loan is not accessible, there has been an amount charged of over R600 after I had transfered over R5000 into the account. I have been trying for the past two weeks to get hold of someone who can help reverse the charge and make my account active. When I got hold of the revolving loans department I was told they have limited access to my account and that I have to go into the bank. I am not able to get to a bank due to my working hours.

Please urgently assist.
