Terrible service and wrong information at Game Wes

I bought a tv,50 inch at Game Westwood in June/July 2014. The tv gave problems a few months after.We thought it was possibly our dstv cabling,we called a technician and had a look.The problem was still there,took it to game in july,no one updated me or sent sms to say i must pick tv up after being looked at despite being promised.I learnt days later that the tv was back and had to be picked and was told there is nothing wrong wih it.I was then promised if a problem similar arises a technician would come and have a look at home.The problem carried on with the tv &amp
