Home Depot Failed to repair a generator I purchased, I used the unit for 18 hours before it stopped working and its been in the shop for over 5 months Redlands California

I purchased a Briggs and Stratton 10k generator June 17, 2016 from Home Depot and purchased the extended warranty. The Briggs generator failed after 18 hours of use I called Home Depot Protection Plan and they sent the unit to Evans Lawnmower shop in Pomona Ca. to be repaired the unit is still under the manufacture warranty and Briggs is working with Evans Lawn Mower to get the unit repaired. Evans Lawn Mower Replaced the generator head and some other miscellaneous parts and the generator is still not operational Cameron with Evans Lawn Mower stated the his tech contact at Briggs has no idea what is wrong with this unit its already been over 5 months. As a customer of your products I am very disappointed on how this issue has been handle and how I have been treated I spent well over $3000,00 for this unit and will never purchase any of you products.
