Edgars / RCS *******!

I am appalled at the service since RCS has taken over the Edcon group. In 2018, I overpaid my account (I normally do) to the amount of R811, in March 2020 I received a call from the head office wanting to know which account I would like the R600 credit on my account to be refunded. I stipulated that it was to be left on the account and I would utilise it on my next purchase. I then received another call In the April making the same request and I gave the same reply. In June I went and made a purchase to the amount of R389 knowing that I would not have to physically pay for it and I would still have a balance left. Well to cut a long story short, I received a bill for the outstanding amount. I contacted them and they could not go back into the old database to see what happened. The lady in the call centre made a request for the history on my account going back to the January. Well this has not been sorted out and I would like to know what happened to my money. Prior to the takeover the overpayment would continue to reflect until I utilised it. So RCS where is my money which you have ****** from me???
