Edcon - gift card redeemed by someone else

Since my 11 August review Edcon has given me a reference number (***/GO) and that is it. What about my money Edcon?

11 Aug Edcon - JET gift card - A few weeks back, when I tried to use my Jet gift card, I was informed that my gift card had already been redeemed via an online purchase. This purchase was not done by me. I have logged a complaint to Edcon via phone and email and still have had no feedback. What is going on here?
