UNFAIR TREATMENT BY STORE MANAGER

I bought an HP Laptop and Office 365 from Game stores on 17 March 2015 at Westgate mall in Roodepoort. It started giving me problems and I took it in to the Key west mall. A gentleman by the name of Tshepiso tried to assist me to get the machine working on several occasions with no luck at all. I decided to take it back with the charger and claim my money back, I spoke to Moira [not sure if she is the floor manager or what] she then explained that it should first be taken to Incredible solutions [IS] before they can decide because it is not theirs. Inconveniencing as it was I agreed. Then I got a message from them to come get the machine. When I got there it was still not working, it was without the charger, IS had formatted it [wiped out] everything. They themselves did not get any feedback/report from their supplier as to what is the problem. Then I was referred to Christopher - the store manager by Moira to try and get a solution, I informed him that I DO NOT WANT the item anymore and I want my money back - what an attitude I got from him - he ended up leaving me there with his staff. It is still with them, they ignored my concern - I WANT MY MONEY BACK, NOTHING ELSE!!!!
