Supper bad and rotten service for AA

I am so disappointed and angry with AA that I am even shaking and it's even given me a headache because of the supper bad service I received from them, I customer service person who has no experience as mechanic declined my claim just because of something the book says according to him he was so arrogant and rude over the phone if he was near me I would have assaulted him, He refuse to send out a quality assessment agent to verify the claim he tells the Mechanic with years of experience what to do and how to do it if this is the kind of service AA gives their customers it's unprofessional, the only thing this person wanted to do was make sure my claim was not paid and he was proud of that
