Nightmare service by vodacom

I Claudia Pikwa bought a contract phone with vodacom last year in june ,in December my phone fell and had a crack so I immediately took it to vodacom for repairs,my phone left for weeks for me to get an SMS to come collect it as they done with it and next thing I get there my phone is not fixed instead they tell me ITS BEYOND EMCONOMICAL REPAIR'S they told me my phone can no longer be fixed so I must take it and buy a new one,I told them I can't pay for a phone which is no longer working they said its my problem not Thiers as I refused to take insurance for the phone and I don't remember ever declining any insurance or being offered one at my point of purchase and now whats worse they won't fix my phone or help me in anyhow,now some other parts of the phone are missing like my sim card tray and memory card. I really didn't not appreciate the way they spoke to me as no one even bothered to explain why my phone can't even get fixed instead they told me it can't be fixed and there's no space for it to be fixed and gave me my phone and left me hanging now Im stuck having to pay for a phone which is broken and being refused to be fixed by the suppliers of it and the manufacturers
