The same thing happened to me if it consoles you.
Someone did me over in the works car park and drove off...just out of cctv.
Had it all repaired and under a month later a guy in a bmw reversed into me whil we were quing to go into the same carpark! I was hoping mad.
Back to the same paintshop - and he paid this time so it was just inconvenience.
Good luck getting it repaired and claimed
Also i have 2nd car now to prevent this sort of thing happning and it works out quite nicely. Fuel economy + i don't have to worry where i park!
