Poor Service

I had my new iPhone 6 for 3 months, which I upgraded my contract with vodacom.I updated my iPhone, but the phone just froze.Took it to my nearest repair centre in Loch Logan Waterfront Bloemfontein and reported it as a software problem.They send it away for, told me it would take about 2 weeks.4 weeks later I still heard nothing and decided to phone them.They told me the phone is not fixed because I did not accept my quote, which nobody in the first place notified me.The quote was for about R 5000 and they told me it is to fix the volume button,which I didn't had a problem with,it was working fine.I reported it as a software problem.The lady at the store where very rude and told me it is not her problem and that I should take it two Apple.I told her that I bought the phone from vodacom not from Apple,she refused to give me her name when I asked.Now 5 months later I still sit with my old phone paying for the new one, nobody at vodacom is assisting me in any way.I bought the phone at vodacom,but they keep shifting the blame to Apple.It is very frustrating at the moment, I have been a vodacom client al my life, but the service is dissapointing an I am paying for something I don't have
