Vodashop manager assisting and arrogant

I upgraded to a vodacom data contract 29/01/2015 with a Ipad air , the wifi of the unit was not working and I returned it to the store the same dae , they say they have a 7 day policy to determine a repair/replacement. When phoning the vodashop vaal mall they do not want to help and the manager Gert Marsh is very arrogant. I contacted vodacom repairs and I store and they have nor received the device from vodashop vaal mall? when I phone vodacom customer care they also cant assist me? so after 2 weeks no device of support?
