I am charged money for your double debit fault

Dec Jan my account was debited twice due to system error. One Debit order failed as i only leave enough for the normal debit order. January i was charged R100 for this. The debit order failed again as again i only leave enough money for the normal amount. Then you resubmitted the faulty amount again on 4th Feb i wasn't even aware of this one After various calls and waiting feedback for days. You paid me R100 extra for money you did not take from me. Then you put through the right amount on 8 Feb via debit order. But now you charged me again for the debit order in Jan that failed due to wrong amount debited. And you charged me another R100 for the one on 4th Feb. Now my account was R200 over the normal amount. I have put in extra to get this to not fail again. However in the end you charged me R300 in total - you paid me back R100. But ALL of this because of your technical error in Dec/Jan . Can my account be fixed, monies owed to me paid back. I have locked a hello peter complaint before. .... and guess what as this is a 3G number, i added my work number as contact number and you investigated that account. Seriously ? Ive spend hours on calls and mails. Acc I***-5 ***)
