unfairness

I am very disappointed with the service I received from foshini and customer services on the telephone, I received a gift card which got lost but I feel its not impossible to replace that since I have had a hassle to even get the card blocked which they could also see still had R500. They required info from me which I didn't even have on my receipt finally after I argued they decided to find the original docket. I also work in a retail store and despite t's n c's its not impossible to use this voucher Since I have the card number now and proof of the purchase. It is really frustrating to go through the helpline and customer services speaking to Lam (supervisor @ Head Office) who can do nothing for me. Why do you provide a service to rob people? What if I hadn't blocked my card and someone did use it then I report it ****** what can your\ll do then? How is that providing security for a customer of your group. I do not understand how this works.what if I came from afar and forgot the gift card but desperately needed to use it on a friend/family during this holidays or it got damaged during a fire @ home?Not a member even asked for my details if it had to come back to their store."
