Endurance Warranty Services review: Denied claim

I took my cat in for repairs. 1st Endurance ask for invoice for shop I had unrelated work done too. I got that invoice they reviewed it and said everything was good. 2nd two days later Endurance asked for another invoice. Got that one and was again told everything was good. 3rd I called endurance 3 days later for up date and was told an auditor was going to repair shop that see what was needed and to get oil sample. At this point even the repair shop owner said they are trying everything they can do not to pay. Day after auditor visited the repair shop I called Endurance and was told everything was good and to have repair shop call endurance so the could get a plan together. 5 hours later the repair shop calls and said they denied your claim. I called endurance and was told claim was denied because my tires are to big. They are .7 of an inch bigger. And it was engine work need that had zero to do with tires. I told the rep I did everything asked of me. The guy that qualified me when I signed up asked a series of questions to get me qualified for Endurance service but he didn’t say a thing about tires. She said he should have asked but it didn’t matter. I told them when I signed up that I bought the car used tires were on there they are dodge factory wheels. I ask could I speak to someone about an appeal and was told no. I asked for a copied of auditors report that states why my claim was denied and was told no. They took my money every month. When according to them I never qualified to there services in first place. Now I have a car at a shop I can afford to fix or even pay to go get because charges to diagnose I can pay for. ENDURANCE WARRANTY IS A SCAM!
