I rent a garage from a local housing association and I park my classic Saab 900 in there. I recently visited the garage to find that they had replaced the roof without informing and with the car in situ. As you can imagine, there is a fair amount damage been caused to the bodywork. I phoned the housing association and they said that they would get the contractors to contact me. They duly did, but the people that I have dealt with so far are rude and ignorant and, although they initially said that they would sort it, they are not communicating with me. As I rent the garage from the housing association and my contract is with them, is it they who are liable to sort out the damage to my car? I thought about involving my insurance company, but don't want a black mark against me for a possible claim if I end up not claiming.
