MR PRICE

I purchased a handset in Feb early this year a Sumsang A03 and i made the purchase with my card. Days later the phone gives me problems I take it back , I get to the store they tell me nothing is wrong with the phone I should continue using the phone and if it gives me any problems then I should come back they will give a new one because I was still within the 7 days. 2 Months later the phones lock button on the side stopes working I go back to the store with my bank statement because I had lost my original slip, they tell me they wont be able to take the phone because I dont have the slip. I tell them but on my bank statement they can see that I made the cell phone purchase there and the worst part of it they also scanned the phones packaging and they saw that the phone was purchased there. They told me that they will not be able to assist I must see what I do with the phone but they will not be taking the phone. Horrible Experience I have received at the Mr Price in Gugulethu mall they also advised me if I want I can go to the Vodacom in Century City MAYBE they will be able to assist me that side.
