Poor Customer Service @ Game Store - Clearwater Mall

Last year in October, I bought a Salton stove (Two plate and Oven) at Game. I was given one year warranty on the appliance. The stove is no longer working properly, one plate is no longer working at all and the oven is also broken. I then returned the stove to the store and they told me that they will have to take it for repairs which will take it up to 21working days, meaning I will have no stove for over a month. They refused to exchange the stove or even give me a refund as I can not at all stay for this long without a stove. How do they suppose I cook in the mean time? The people I spoke to in the store did not care at all. Same with their head office. All were not caring about the situation this has put me in and could not assist at all.
