Carchex Repair bill $870. My portion $537. Whats the use of having a warranty with these guys. Internet

 Bought a warranty from Carchex. Salesman stated that if I ran into any problems with the parts that was covered under warranty that all I had to come up with is a deductible of a $100 dollars and find a certified repair shop of my choice and my car would be taken care of. Eight months later my water pump fails. Had the vehicle towed to a shop, thx god I didn't take it to a dealer. The bill, $870. I paid $537. That just $100 deductible crap doesn't exist. Talked to a representative and got the pretty much your screwed speech. Carchex just pretty much handles the part and a few hours of labor to put the part in. Hoses , belts and any other thing that needs done even though it may relate to the part that's being restored it's on you. Don't do it people.
