I feel for you mate but the provisions of the warranty are clear, and I'm sure it was in the back of your mind when you chose to take it down the quarter. That said, perhaps try a different dealer that'll work a bit harder on your behalf and sell your case better. A lot of yelling at Ford here, the dealer is in the middle and doesn't always do you any favours. Such dealers that actually give a stuff exist here in SA if no where else
Good luck.
