Customer to pay for Poor Quality Card

I made an account purchase at Mr Price the way I normally do and like always the consultant could not scan the barcode on my card. He punched my card number in to finish the purchase like all other consultants I have encountered before. This consultant however went a step further by trying to get me a replacement card.<br> <br> He called the Mr Price offices to arrange for the new card. I decided not to go forward with the card replacement when I was told that I would be billed for the card. The call centre agent assisting me at the time could not make me understand why I need to pay for a card that I did not loose or damage. The barcode on the card started fading after normal use. I asked to speak to her superior (Cameron) who was not helpful at all. He told me that If I don't pay for the replacement card then I won't be able to make purchases so that is my problem. What he fails to understand is that I don't need to purchase from Mr. Price not does any other customer!!!! <br> <br> Cameron (superior) advised that's it's fine for me to take my business elsewhere and that is what I will do.
