i feel for you, i used to live in a area that had alot of b&b's that contractors would stay at, they often couldn't give a damn about their work vans and within 12 weeks of me living there i had dents/scratches on all 4 corners of my car (didn't have designated parking so parked either side of the road) thankfully i never had any damage this bad, people not owning up to their mistakes are just a pain in the ****. i've also had someone open there car door into mine causing a pretty decent dent whilst i was sat in the car, they didn't even look! just walked off to put their money in the parking ticket machine, when i collared him about it when he came back to his car all he had to say about it was "how do you know it was me?" douche...
