Endurance extended warranty

My purchase a vehicle in July of 2025 also purchased endurance insurance got the Platinum package. Which happens to be the best of the service plans, the first time the engin light came on they didn't cover cost. About 3 months later light came on again this is the and was told needed a new engine. We were asked if we ever had engine flush answer was No because since we never had a engine flush they would not cover. So once we send we are cancelling we were told we need it to be notarize really to cancel a service. Never heard of that in my entire life. That's fine. I will never ever use them again and I'll tell the world never use them again. You're horrible.
