Edgars Charges NCR fee but report wrong information to NCR.

I have a store account card with Edgars. 4th of Feb I went in to pay the account, Until the 16th of Feb I kept receiving calls that I did not make payment. I went to the store twice that month to inform them about the payment. I was told Edgars system had a problem with allocating funds to accounts, I was told i am not the only one with the problem. When calls persisted even after, I went back, demanded to speak to a manager of the store, they refused, instead a Call was made to Cape town, i explained my issue to Lindokuhle Mhlati who then Escalated the matter to Rifqah Lucus in Cape town. I dont know if I should say Rifqah is useless or the escalation at edgars is useless. She did nothing. a week or 2 later I followed up, Called for Rifqah - She doesnt answer phone calls either, i was refered to Lindokuhle again. They send information to NCR to say i missed a payment, yet on the statment of my account, it says payment was made on the 4th feb. With my search i found out they updated the NCR on the 8th of Feb, From the 4th to the 8th account allocations were not done even after, and this became my problem. I sent them proof the whole of March asking them to rectify their mistake, no response no action nothing. i tried calling their cape town office, they do not answer phone calls, they keep transferring you to wrong departments.

My question id why do they Charge us the NCR fee if they update wrong information and can not correct it. Poorest service at that department.
