Complaint Review: Endurance

I purchased my warranty 6 months ago, I did not have any pre-existing condition, car was running fine. Last month the check engine light came on, I took it to a dealership and they told me that the car has about 4 minor issues, any way, they called endurance, and guess what nothing is covered, I ended up paying for all the repairs. Second I cancelled my policy they told me I have to send in a notarized letter with the millage and they would contact me. well 3 weeks passed by, no word from them, called them up( after 40 min on the line) they told me that they received my letter, but they don't know how much money I will get back, but somebody will contact me shortly over e-mail with all the information. Well another week passed and no word from them, called again , finally got an answer, well not a happy one. After making a deposit of $279.60 and 4 payments of $139.80. and they did not spent a dime on my warranty they decided that I am entitled to a refund for $344.40. Now this is hilarious, they keeping my $500 and stating that I should be happy that I even get back that much. I'm sorry but what did you do to earn that money, they stated that the initial deposit is not refundable, because that was for the set up and to send out the membership booklet. I'm sorry but since when does it cost nearly $300 to print  a 10 page booklet. They are all about getting your money. If you don't want to waste your money, do not sign up, nothing is true what they are telling.
