Standard bank debits my account for an unauthorized loan

<p><span style="color: #6e7e95; font-family: Arial, Helvetica, sans-serif; font-size: 17px; line-height: 17. ********** ********** 3px; text-align: justify; background-color: #ffffff;">I have been with Standard bank for many years and have taken one loan with them previously which I settled. Then took out another RCP loan in June 2016 of which the deduction is R1054.00 which I did consent to and is paid by my fiance. The problem now lies where Standard bank keeps deducting an extra R1032 from my account monthly for another RCP loan which I know nothing of. I have been called several times by standard bank agents demanding payment and I would explain that I have not taken out 2 RCP loans. I have even been at the branch to resolve this. It was seen to be a mistake from their side as there is no trace of the loan when checking their records and can't see loan information. The payment request calls have stopped but my account was debited again this morning.I don't know what else to do because this is a serious inconvenience as there are history notes placed on my loan accounts so I don't know whether it is just ignorance or bad client care.I have things to pay on my side and I'm now going to be behind with my dues for the second month because of Standard bank. I have been patient but I feel like they are doing nothing about it because they are not even giving me feed back and updates to put me at ease. I am not happy about this because all dues to them are paid to date and I am worried that my credit record will be adversely affected.</span></p>
