Sears Canada Inc

I bought an electronic item from this company, and had purchased the extended warranty. After I got the item home, I had problems with it. I had to phone the retail company. the only thing I am concerned is that if I did not use my warranty then I would be entitled for my money back in three years. It was not my fault, so why I should be responsible to get it applied against my extended warrantly, in only ten days.
