Full-timer unhappy with Extended warranty issues

I had some parts replaced under extended warranty, Western General, they were Power Gear parts, they told me it would be five to seven days, but they would cover the part. I opted to pay out of pocket to get it overnighted. If I were you that is what I would have done, especially if I was living in it. (Just my 2 cents).
I did this through my mobile mechanic.

Hope it all works out for you.
