Store Manager Clearly Unresponsive

My wife purchased a cover for a P8 light on the 27/8/2015 IN0052T*** at the Blue Route Vodacom after ordering a phone via Vodacom direct. The phone is unavailable due to stock outage and we have decided to get a different model, making the cover useless to us. On Sunday 6/9/2015 we tried to return it (unused and sealed) to the store and was told that we can only receive a credit. I actually wanted a refund, cash or EFT back into my wife's account. I was advised to discuss it with the Manager Ebrahim. I called twice on the 7th and left a message with no reply. I also emailed Ebrahim at 5:18 on the 7th and my email was read at 5:37. I also called on the 8th and still no reply or call back. I find this highly infuriating as for R99, I cannot get a straight answer. Pathetic service<br>
