Hawk,

That IS a royal ripoff.

This is another example of lousy service men. It's so hard to find good honest help these days.
I don't know if this will work, but its worth a try.
This company and their man are licensed by the state.
I'd contact your attorney general's office with the details before getting the new stove. Maybe you'll be able to get through and you'll get a staff member who will help.
