Standard Bank vehicle finance -****mers

My mother passed away in November 2022 with an outstanding debt from Standard Bank vehicle finance.

We proceeded to contact Standard Bank and sent a letter to continue monthly instalments on one of the vehicles since no one qualified for vehicle finance at the time.

We have been paying the amount as agreed which was the monthly instalment amount of R10500 since Standard Bank accepted the payment arrangement.Last month around 15-23rd April , my sister who is the executor of the estate contacted Standard Bank to get the outstanding amount. She was told on the call that the amount outstanding was around R20000 and some odds.She called again and once again that amount was provided to her.

She requested that this be sent in writing so that she could make arrangements to settle the amount. This email was never sent to her. On the 23rd I followed up with Standard Bank on the statement we have been waiting for and I was promised that they would get back to me.

Standard Bank only rep**** today and suddenly the amount is now R77000 and there’s apparently some arrears interest which we have never been told about since we have been paying the instalment monthly.

Standard Bank has realised that the car is finally being paid off and suddenly new amounts which were never communicated to us are popping up. We are also being told that the total outstanding and the arrears amount is two different things. I mean this is very clear that this amount is being made up to continue ripping us off.
