Gift Card balance dissappears

I bought a gift card on Momentum online on 24 Aug. The sms voucher was used to purchase shoes, which were returned the following day. The Clerk informed me they cannot refund the cash amount but did offer to move the balance to a gift card. I agreed to this and requested that they move the balance to the gift card and print an enquiry to show the balance.<br> <br> On Sat 12 Sept I tried to use the voucher at CNA at Rosebank Mall. The transaction could not be completed as the gift voucher system was offline. The manager on duty, Mary, then tried to call the gift card centre and had no answer after holding for an hour. I then had to be embarrassed by asking my friend to pay for the purchase. Mary promised to refund the cash once the gift card system came online. She phoned on Sun to confirm that they could not find the card on the system.<br> <br> On Mon 14 Sept I went back to Edgars Rosebank to find out why my card is not working. The manager stated that there was no transaction on the return date, she could not assist further and would refer to IT (48h) to investigate. She could not trace the balance using the voucher enquiry and pointed out that the gift card no did not appear.
