Mouse trap

I am so disappointed that in these difficult times my insurance is uninterested in helping their clients. A mouse got into my new vehicle and chewed through cables and wiring. Kingprice has flat out rejected my claim regardless of it not being my fault. My vehicle was parked in my garage and they say my comprehensive cover is only for accidents (surely this is one). I've now been quoted 33k to fix the damage and cannot afford to have it fixed. Despite multiple efforts to reach them to discuss the matter and get some assistance I've been ignored. I will be moving to a better insurer who is also offering COVID19 relief. I'm disgusted by the service, after years with Kingprice this is how customers are treated.
