Claim rejected

My caught alight on the 10 April 2015 between Komga and Bhisho , I submitted a claim to AIG insurance company via the strata insurance brokers, I have sent all the documents they required from me to process the claim, they took two weeks to give me a courtesy car referring me from pillar to post. I kept on calling Carmaan from Strata insurance brokers who communicated with Sandy Tompson at AIG but I noticed no progress, I contacted AIG myself speaking Sandy Tompson who was dealing with my claim. AIG knew the outcome of the claim before receiving the report from the assessor because Sandy Tompson at AIG insurance told me that my claim is not going to be paid because the accident is mechanical related, I asked him to send me the document which is rejecting my claim , she said \ we are still waiting for assessor"s report\"" "
