Loan Process without consent

I am a former student at UKZN Westville campus and I app**** for a loan early January this year, I completed my application form and hand delivered it in one of the Fundi branches in UKZN Westville Campus and I was assisted by a consultant named Victoria who informed me that she will be contacting the applicant (my mother) if the loan is approved and they will agree on the terms of any contract. However the consultant did not even provide me with any reference number or any information so I couldn't track the progress of the application. An sms was never sent to my mother and she was never called so I took it that the loan was unsuccessful and I didn't enrol to study this year. The problem started when a sum of R30 00 and some extra rands was taken out from my mother's account everytime she gets paid. Today I found out that Fundi did approve my loan and paid the university the fees however neither the applicant (my mother) or I were informed on this and there was no agreement on any terms and conditions we did not even sign any document except the application form. Now my mother is being debited every month for something she did not agree to and this is causing a rejection of payment for all her other debit orders. I enquired about this today by going to the same office and speaking to Victoria who was unhelpful and rude, who told me the applicant should write a cancellation letter and she will forward it to the head office but this coming 15/04/2018 my mother will still be debited. And later on the day today an sms was sent to the applicant stating that her loan was approved, this is the sms we waited for months ago and it never came
