Vodacom Norwood - worse than second hand car sales

<p> This is my 20th year with Vodacom. I've moved my whole family over. I bought a guess cover when I bought 3 iPhones this year, which are still under warranty to now be told by Vodacom that it is a reseller and not responsible for guarantees. 3 weeks later the manager at Norwood Vodacom tells me that it's up to sales rep & his hands are tied. I'll have to wait much longer to replace the cover. He can't replaced the cover. He doesn't have the authority. Then & more importantly the iPhone 6s doesn't work and is still under warranty he says in a very uninterested way that I need to take my phone somewhere else -EASTGATE to be fixed because Vodacom does not fix the phones it sells. Neither photos nor message services works on the phone. Over 20 years I have bought on average 2 phones a year & now with my family 4 phones every two years. Is this how I can expect to beer treated by Vodacom as a valued client? </p>
