Faulty Iphone 8

I went to Vodacom 4U Mall of Africa on Saturday(21/10/2017) to do an upgrade on my contract and get an Iphone 8 as it was released to the shop the previous day. Excited as I was with my first time experience of an apple phone it turned out to be a nightmare. I collected the device around 13:00 and around 19:00 the touch functionality on the bottom part of the phone had stopped working. I slept with a heavy heart and the following 22/10/2017 I returned the device to the store and was told that the device will not be swapped before it can be assessed by Apple repairs and promised that the matter should be resolved by Wednesday(25/10/2017) by the Manager and Sales Consultant.

When I phoned the store today the sales consultant said the Apple repairs were not working yesterday and the matter has not been resolved. I phoned Vodacom on ********** and they told me they don't understand why the store couldn't give me the phone. I currently have an upgraded contract but don't have the device. As far as I am aware I have 7 days to cancel the deal but that was not my intention but felt let down by this type of an experience more especially from devices that are rated to be the best in the world. I have given the sales consultant up until 16:00 today to resolve my dispute or else I will have no other options but terminate my network services with Vodacom.

Someone please get the Manager of this store to resolve my dispute by COB today
