Weed Eater One

My Weedeater One has been in an authorized repair shop since 28 July 2012. They keep telling me it's because they had been waiting on parts. It's now Oct 12th and my warrenty has expired. The shop suggested I contact you about extending my warrenty by an equal amount of time since once I finally pick it up, and should it break again, they would not be able to fix it under warrenty guidelines. I feel it should not take months to get a lawnmower fixed due to a lack of available parts. This delay is not my fault and I feel I should not be penalized for this.
