STILL NOT FIXED

I have been to Bryantson 2 times for a phone that does not work. Both times informed that it has now been fixed. Initially I was told the reason it goes black while busy with it is because of software. A day after receiving it back did the same, this was to a point that it completely went black and there was no display. After a week I have received the phone and another problem now, the playstore application is not working. I am not prepared to send this phone to Bryanston for the third time. I don't want it repaired again I need a new phone thats not going to give be problems. I bought this phone because I trusted the brand, while people were insisting i buy an Iphone. \As per Consumer Protection Act: "A supplier cannot force a consumer to choose to have the goods repaired"
