That looks nasty, can only say that a similar thing happened to me, but in a BMW and at the vets, and I ended up paying for it myself as the vets simply did not care, parking at own risk etc, it was about £1000 as I needed a new bumper and fixings etc, but was less hassle than claiming, although I had protected no claims I'm sure thay would have put my premium up anyway.
Good luck, hope it all gets sorted soon
