account debited without my knowledge

I was debited an amount of about R2007.00 of which I'm still puzzled what is it for, because I didn't get a call or notification prior to the transaction. <br> I tried calling the customer care and I'm sent pillar to post. <br> I've gone to the branch for assistance and I wasn't assisted since I wanted a reversal back to my account because it's an inconvenience on my side. Had I had been notified in advance it wouldn't have been a problem because I would know about it <br> <br> All I need is a my money to be reimbursed back into my Account.
