Insurance problem after departure (Passat 35i)

Hello community, I would like to have a problem there! 🙁 On the facts: I was broken up on 07.08.09 the Passat 35i and the “NEUE” mountain bike in it was stolen. Since the Passi is only insured liability, I thought that the damage could also pay the household insurance. The legal conditions for this are given. Well, on 18.01.2010 I get the cancellation of the insurance, since NO SINGLE DISCUSSION POURS can be recognized on the car. According to contract clause m In this case, the building is a parking garage and the locked space of the cars. As far as there are no problems with the insurance… further. Insurance cover also exists: 1. if the thief uses false keys or other tools that are not intended to open these locks. 2. in other ways, in the conditions specified, enters the space of a building. Now I am, as a policyholder, i I am sure you can!!!! (…there was something with a tennis ball and the airbag of the ZV????) Well the question: Is there IRGENDWO expert reports or attempts that prove this fact???? I need something powerful to prove what I can add to my objection. I could of course also invite the insurance expert to an appointment and then call the ADAC… he makes the car “EXCLUDING SPURE N” in a few seconds. 🙂 Many thanks in advance and greetings from Ronsdorf.
