Debting account

on the 23/09/2015 I realised my current was overdrawn. When I queried it, it became apparent that I had been debited by ABSA for an amount of R2430.40 which had pushed my account over its limit. When I looked into it, I realised that I had been credited twice during August. No one at any point felt it was necessary to inform me that my account would be debited on this date. I have subsequently been charged by my bank R120 for honouring this reversal. This is not the first issue I have had with my pebble. I would like the fee for R120 credited to my account. A letter of apology to my bank explaining that I had not been informed of this debit that was going to occur. I would like the pebble collected and my relationship with ABSA to terminate permanently.
