Mistreated and unappreciated Customer

If I must say this I will never ever purchase a cellphone from any Cell C outlet ever again , it is downright pathetic and sad to think that I had to book my Samsung J7 Prime smartphone in 5 times for repairs at the Liberty Promenade Mitchells Plain Branch where I purchased it and for a brand new phone that I bought last year March 2017 only to have it return to me with the exact same problems reoccuring over and over with the homescreen centre button not functioning as well as the return arrow and multiple software glitches and screen freezing when I enter an application it shuts me back out again I have booked the phone in so many times with helpful Ryan Gertze but what angers me is that the staff do not seem to be concerned. I have expressed my frustration with the branch manager Shireen Scott only to receive no concern to my plight whatsoever and horrible attitudes from the staff truly despicable and they openly show that they don't care when I asked for a spare phone they presented me with a used phone that looks like it came out a garbage can. I am definitely going to make contact with the consumer protection as to what my rights are and what I can do as I am paying R875 p/m for My J7 Prime and my brother's Huawei P9 incl Insurance which I think I have been more than patient with these people long enough. Whatever you do people do not buy your phones here as it is not only me experiencing these problems many people come back to the stores with complaints about their phones.
