I'm so sorry. I know how ticked and disappointed you must be.
Hmmm....wonder what an extended warranty actually costs them. I know the finance manager tried to hawk a couple of them to us for $3-3.5K. It wouldn't hurt to grab it while the offer is on the table, especially if you plan on keeping the car.....before they change their minds about giving it to you. It's really the LEAST that they could do for you since you'll be out of your car for almost 4 months IF they make the 5/14 deadline.
I sincerely hope that she comes back as good as new.
