Bad service from team - Sechaba Malasele

Every other month, for some reason a debit order which I have not authorized goes off my account and I need to call in to ask them to reverse it. In the most recent case, same thing happened and as usual I called and asked to reverse the debit order. While on the line I asked the female if it's possible that I get sight of who keeps debiting my account, she said sure and told me the reimbur*****t of the funds takes 48 hour. A day later I get a deduction from my account from Std Bank, I called in to check what the deduction is for ant i'm told it's because I asked to see who keeps debiting my account. I tell the gentlemen on the line that I was not informed that this would come at a charge, he argues with me and says there's nothing he can do about it. After a 5 minute back and forth, he speaks to his manager who says he'll listen to the recording and get back to me. It's been almost a month, no word from the manager or anyone. I did ask for the manager / team leaders name and was advised that his name is Sechaba Malasele
