Useless Covers!!!

Terrible policies that do not make sense. I took a break cover and extended warranty cover with them, when I needed to replace my breaks I was taken from pillar to post, I now have an issue with my gear box to which they claim they cover but they tell me that the part number they were given by the dealership they don’t cover, it’s just a terrible company , the only thing they do cover is extended service. Imagine taking 3 different covers with them and 2 not being covered. Terrible to say the least, now I want to cancel cover they want me to serve a 21 day notice and still deduct my account? Madness if you ask me!!!
