Utterly Disgusted - Faulty Products

I have been a client with them for over the past 10 years and have never received this pathetic treatment from the many consultants I have been dealing with. I took a contract in 2015 and have had numerous problems with the phone. I handed it in at one of their branches in January 2016 who informed me that it will take up to 21 days to be repaired at their repair centre. After the time I had to query it on my own. I was told the phone can't be repaired and I need to close a new phone because it was discontinued. On 29/01 spoke to Tshilio regarding the problem who advised I should cancel take new contract case no. ***, I then called back on 1/2 spoke to Sepa, advised I should call sales department, called Tuesday 9/11 spoke to Frans, transferred me to supervisor Sizwe. I called him back on Tuesday 16/2 and he is still not willing to help after explaining my grievance and inconvenience.contracted to me and it then be discontinued and becomes my problem. I want the exact same phone as I also see Vodacom currently has it on contract or another phone that I am happy with at the same price which was what I could afford. I am so disgusted that this becomes my problem.
