Absa bank failed me once again

Since last year I have had issued with my Absa account, where they deduct an amount of R57 each month for my account going into a minus. it was resolved but now the problem is starting all over again. They also deduct debit orders which I do not have on my account and they deduct these debit orders on dates which I never agreed apon, then they charge me fees for the debit orders that reversed. How is this my fault? I have called the call centre, I have logged a complaint, but every month this problem continues, please help because I'm about to change my bank. <br> <br> regards,<br> <br> Lynne Du Preez
