I'm no stranger to this game. I skipped the nonsense and go right to the corporate contacts aka the bigwigs. That's what I've been doing. Still not getting anywhere but that doesn't mean I'm quitting. This isn't my first rodeoIf at first you don't succeed, try again.
I say this because a phone call always goes to someone else.
If they deny you and everyone else the 1st time and 50% of the customers go away, they are ahead. Keep pressing and you should get better results. If you keep pushing, they should eventually cave to their warranty.
I know it shouldn't have to be this way, but that's the way it works.
Best of Luck
