Poor Service Delivery

November 2014 I took my S4 in for a cracked screen repair. I was informed that there was no stock and I should come back in a week. It has been 11 months, 6 visits and many frustrating phone calls later and I have yet to receive assistance. I have left my contact details with numerous employees on many occasions and I don't receive a response at any time following my visit. I have made a point to visit the centre as often as I can in hopes of being assisted but I still only hear of lacking stock. How can it be that for 11 months there is no stock? This is infuriating and absolutely inexcusable poor service delivery
