Endurance Warranty denies claim on a USED Car. States Customer is Responsible for damages before she owned car Northbrook Illinois

I purchased an extended warranty on a car that I bought USED.  I took the car in to be repaired.  The mechanic did the diagnosis and was told that based on their intial find the engie would need to be broken down more so an adjuster could come out and look at the work.  To do this cost me an additional making the cost go from $180 to $300.  I paid the additional charges.  

It took the adjuster 5 days to even come out and look at the car.  All the while because it had not been determined if the claim would be paid I was not able to get a rental.  Once he came out the mechanic stated that the adjusted didnt look at the car but just went by what was said.  The problem was found to be a previous repair that was done to the car.  As stated before, I bought the car used so I was not aware of nor did I think that the car would had the damage that they stated.  The only way that would have been found out is to have the motor broken down.

So the adjusted denied the claim stating that the damage that was done to a total differnt part was due to a repair that I had no knowledge of.  When I asked the rep how I would have know that the issue was there he told me that he had no answer for that but that I had just been "screwed" by buying a faulty car and that there was not a warranty company anywhere that would honor their policy.  I again asked him how was that fair to me since 1. I am not a mechanic 2. The car ran for a year without issue 3. I bought the car used and by pulling reports I didnt see any suggestions that the work they said was performed was ever done.

I just want to get my car fixed.  I bought and paid for a warranty and now am not able to get any results from that.  I feel like they have used every little "wording" run around to not pay for the claim.  In looking at the internet I see that I am not the only person that is having that issue.

To say the least the rep told me that at this point I was out of luck and it was nothing he could or would do to make this right.  I told him I wanted to cancel my policy and he stated that was fine with him.

I wish I could spread the word all over so no one else would have to do through this, a month later still no car repair.
