Not happy with the service

I took my phone into Vodacom green point on 5 November 2015. I was told it need a software upgrade but when they tried it didn't work. The guy then told me to have my phone booked in. Before I even spoke to the lady at the other counter I was told they will not accept my phone as there was a crack in the screen. So Im telling her upgrade software has nothing to do with my screen. At the time my phone was just on 6 month old. She then booked it in but not sure if they sent it away cause then I got a call to say it back there and they not going repair it. I then e-mailed none stop and all I got was empty promise. I asked to speak to some more senior and he said he will call me back within 24 to 72 hour to date nothing. They were prepared to offer me a new phone at a cost of R1700 that I don't have. I have been a customer of Vodacom for more than 10 year and never thought I would ever go thought this. So now I have been with out a phone for more that 3 months and nobody responds to my e-mail or call me back. This is really frustrating as I'm paying for a phone I have no use of. I never expected this from Vodacom.<br>
