Worse Aftersale Service ever.

I have had the most unsatisfying service from Whirlpool aftersales. The glass on our gas stove shattered while we were cooking. We sent an email and after utter dissatisfaction, Whirlpool had agreed to replace the glass. When the technician came out, by the name of Moses, he started finding faults on why he does not want to change the glass, yet he had the glass with him. He was extremely rude and had an attitude in my house. His customer service is up to ****. All I need is our glass replaced as we are still within our 2 year warranty. I need this resolved and I need an answer today or better yet report this this ***** company to CPA and Ombudsman.
