WHY HAVE PHONES, WHEN NO ONE ANSWERS THEM

Just over a week ago, I purchased a double door Defy fridge and Samsung microwave from Game(Pavilion). That evening upon opening the microwave, I found that there was something loose inside, so took it back to Game (CityView) were they exchanged it for me. Upon bringing it home and using it, I found that it does not heat evenly, I tried it for the week to follow and find the same problem. The fridge was also delivered by Game and a 5 year guarantee is being offered by Defy instead of the normal 2 year guarantee, but I haven't been given any documentation stating this. I have tried to contact both branches telephonically to query both my concerns, but the phones just ring and ring without answer. I tried Pavilion for over 15mins today without success. It seems that Game prefers the bad publicity of always being put onto Hello Peter, as this seems to be the only way of getting a timeous response from them.
