Unauthorised debit

Good Day, <br> <br> My account was debited on a day I did not authorise. I was in communication with Elzaane Conradie who I asked to change the due date from the 23rd to the 30th of every month. She said the only way this can be done is if I put a debit order on my account and the arrears are paid. I agreed to this. <br> <br> My account was debited in the early hours of the 24th with both tge arrears and another instalment which was due on the 23rd. There was no money in the account and I now sit with two 138 rand charges for this. <br> <br> The debit was only supposed to run by her own account after the arrears was paid of which was not done by then so this should not have happened. <br> <br> I want the debit order removed off my account and I will continue paying via EFT and my charges returned. <br> <br> Many Thanks<br> <br> Jonathan
