REFUND ME MY MONEY

I have been Standard Bank client for about 15 years now. About 2 years ago, I opened a Standard Bank Credit Garage Card. The agreement was that they will deduct a sum of R1100.00 per month and this continued seamlessly until the Credit Garage Card was closed about 7 months ago.The issue is that they never stopped deducting the R1100.00 monthly amount from my cheque account irrespective of the Credit Garage Card being closed. I then lodged a complaint and asked Standard Bank to refund me. I called almost all their departments to resolve this instead it became a finger pointing issue,it seems all their departments don't know how to refund the sum of R8700.00 they have been debiting from my account. I lost count of how many times I called their head office through their branch in Bryanston Johannesburg (NICOLWAY Standard Bank) instead they keep promising me that I will be refunded before close of business and offer me a SERVICE REQUEST NUMBERS with no solution. This has caused a huge inconvenience on my side and a huge disappointment that until today this issue has not been resolved and non of standard bank consultants has taken liberty to call me and advice on this issue.
