Vodacom does not care!

My I-phone 6+ has been sent for repairs for the touch screen not responding/freezing for 5 times since October 2015. My supplier told me that it is now regarded as being a non-warranty event. This is unacceptable to me as for the best part of October and November 2015, I did not have the use of my phone, and still it is not fixed and in their posession. I called the Nelspruit Vodacom repair outlet twice to tell them what the issue was. Upon phoning Vodacare, the consultant refused to transfer my call to a Supervisor. First , I was told that my phone had not been booked in in Nelspruit yet. After I told the consultant that I have an SMS stating the contrary, I was told that no fault can be found on my phone and two numbers were given to me, so I can call the technician and tell him what the problem is. I called both numbers at 15h08 and 15h09 during which my calls were not answered. My phone's touch screen freezes/stop responding at random. If I reset all settings and reload, the screen works again for a day or two, where after it freezes again. Two weeks ago, I wrote a mail escalating the matter and demanding replacement. To date, no response and no phone! Vodacom does not care!<br>
