Shocked and Disgusted

I visited Edgars Bedford Centre on the 30th July and paid my monthly installment (R900) using my Debit Card. On the 9th August I paid another installment at Edgars Bedford Centre of (R1100) using my Debit Card once again. I received sms notifications from my bank indicating that the monies had been taken from my account and went about my business for the remainder of the month. On the 9th September, I received an sms notification that Edgars had debited my account an amount of R2000 for payments referring back to the 30th July and 9th Aug. I am mortified that even with proof on hand that the payments went off my account (SMS notifications, slips provided from Edgars Bedford Centre), Edgars remain adamant that there is no duplication and that the deposits had to be taken. Not only was my money taken on the 2 initial payment dates, I was also debited a further R2000 (2 months later). I do not have a debit order with Edgars. They had absolutely no right to enter my account and take more money from me after payment had in fact been made on time and in full. If payment was not processed, why did Edgars not call me to remind me to pay my account for the 2 months? I will tell you why... BECAUSE I PAID!!!!!! I am outraged and absolutely disgusted with Edgars. As a loyal account holder of over 10 years, having never missed a payment in all this time, I sit with rude customer services consultants who can only tell me that there is nothing that can be done and that the money will not be returned. Really Edgars? Really? I am beyond upset with Edgars
