Toshiba L300D

I have a Toshina Satellite L300D that i bought in April. The left click button for the mouse is broken it is kind if caved in. I called the store in North Bay and the guy actually told me it is pretty common. I cannot afford to loose my computer for three weeks. Is there any site that can repair this problem in the store or saying that is there a store in Alberta (Grand prairie, Edmonton) that would be able to fix this problem. Other than that do you have any suggestions on getting this repaired.
