Pathetic Customer Service!!!!!

I approached Edgars Cresta After 11am Today to return 2 item that were purchased. I went to the customer services dept. and was first assisted by two young ladies - Jacky van Schalkwyk and Teballo Motswene who I gave clear instructions to. After about 5 or 10 minutes, they handed over to Rameo Motsieng and Sinazo Fumbalele who I gave instructions to again telling them that the funds from the items that have been returned must be paid into the edgars account and then we will process the items that I have now taken. The items were processed and I said that I will pay the difference into the account.Sinazo said that the difference is R443,,,,,, so I transferred R450 into my cheque account and asked him to debit R450.00. He swiped my FNB cheque card and debited 1099.80. So I noticed this on the slip and said to him and Ramo that there is a problem with the amounts and the available balance was 656.... They decided to redo and reverse whateve and also tried to reverse the funds back to the cheque account but the system rejected it. All this time I had to stand and wait. This customer experience was suppose to be during my lunch hour. the two managers refused to assist!! Plse call me !
