GIFT CARD LOST

I am highly ****ed off with Markham's at the moment. If a gift card is purchased and then lost, please do not assume it is treated like money and cannot be claimed. Why is a gift card docket than issued? When I purchased my gift card on the 26/11/2014 I distinctly asked the cashier at Lenasia if the card is lost what can I do, and Lizzy informed me that I can use the Gift Card Docket and keep proof of payment. Today when I call in she informs me that she does not remember saying this and that it is treated as Money. Saturday at Markham's Southgate I got the same response as well as Monwabisi ,Basil and Tanya from customer services. Now Markham's, please kindly explain at the bottom of the receipt is a transaction number. Clearly this number can be entered onto the system, the vouchers purchased can be identified, and surely the one that has not been used can be cancelled and re-issued to me. It seems like a simple procedure that someone competent enough can perform. I am truly exasperated at the level of competency and service offered by Markham's.
