RCS Poor Treatment of Paying Customers

I opened a credit card account with Makro at Wonderboom in Pretoria. After purchasing with the card I requested to make a a Debit Order. I was informed that I had to request my bank to give me some letter. I then asked for an alternative method of payment, whereupon I was given a number that I could use at any Easypay point to pay. For 6 months I made payment using this number. I’m now being told I was paying into a wrong account and should go to the store where I paid to get the money paid into the right account. All the stores tell me they can’t reverse but RCS should. I’ve submitted proof of payment several times both with Makro and RCS but I am getting no assistance. I have never received even a single statement from RCS or Makro except for calls from their collection agency informing me of my being in arrears. I get sick when I hear anyone mentioning RCS or Makro and am considering taking them to the Consumer Council.
