Standard Bank worst customer service

Standard Bank provides the worst of service when it comes to concerns regarding my account, I'm experiencing unauthorised debit orders going off on my account, I immediately contacted the bank to have it stopped but I was advised that they cant do much for me and that I have to phone in each time to have it reversed which is very frustrating because this debit orders go off more than twice a month. I simply decided to change banks but now I'm still having the unauthorised debits going off which led to the account being overdrawn, today I made my 7th call to the bank to update them on the issue but once again no help at all. I work 7 days a week and have no time to spend hours at a bank arguing about my own money. I would like to have the debits removed and close the account. I do not want to waste more of my time with this can someone just get this account closed down IMMEDIATELY?!
