Unothorised debits and failure to effect instructions on a bank account

I have been banking with standard bank since my varsity years back in the 90's. In 2013 I started noticed Naedo debits of R99, R79 which I didn't know, usually amounting to not less than R500 a month. I notified standard bank, and their response was always "ask those companies to stop the debits because we cannot do anything on our side". hello, you are able to allow debits to go through without my permission but cannot stop them at my instruction. Who's interest are you exactly serving, at whose expense? I had always maintained that I have no idea who those companies were. I forget to reverse those debits within forty days standard bank would refuse to reverse them without a fee. I got tired of all this ad decided the way out was to close the account. Now standard bank is telling me that even after closing the account, any uncancelled debit will still go through and I will be liable to pay. How do I close debits that I did not initiate in the first place? I have asked them to close this account 6 weeks ago, at that time the account had Nil (zero balance) . For three weeks I didn't hear from them besides me sending follow-up emails. In the forth week, they effected the service fees etc, then those unauthorized debits and other debits which I forgot to cancel. All those debits debited from the overdraft since I had no money in that account, the account to me was non-existing. Now they are saying I must pay those fees before they can close the account. What game is standard bank playing here? why were they waiting for when I had instructed them to close the damn account effective immediately? If my authorized debits which I forgot to notify didn't get any money they would have called me, in other words it shouldn't be standard banks problem that my debits bounce, theirs is to do as I tell them. standardbank, the relationship we ad is over, please accept it and move on! get your R99 debits from elsewhere, not me.

Please close the damn account!
