I submitted a claim for scratch and dent, I explained what happened and now they are telling me that they won't cover that because at the boot I was bumped by another car, so I asked them that what about the part that I was not bumped by the car. They said when they reject one the reject everything, I am nit happy at all, I've sent the email to complains department on the 27th even today no response. I never received the policy documents to tell me what's covered and not up until I sent the claim.
