            Complaint Type:
            Service or Repair Issues
            Status:
            Answered
            I purchased a warranty for a used car and after one major repair last year, my engine has failed. This company will not only not pay the $4000 they are requiring me for an engine tear down to verify the diagnostics provided by the service company, they are valuing my vehicle at least $6000 less than what dealers are selling these for in *******. I paid $17000 for the vehicle and $7200 for the warranty to cover myself, and have already paid an additional $5000 out of pocket on the previous repair. I work selling goods and warranties, and this is just terrible business practice. If you are a womans buying a luxury vehicle and have little knowledge of cars, please stay away from Cornerstone (Xtended plans eg. XP-1,2,3,4).

            I OPENED AN EXTENDED WARRANTY ON MY CAR AND CHANGED MY MIND. I CALLED THEM TO CANCEL AND I NEVER GOT ANYONE TO ANSWER. I LEFT A MESSAGE SO THEY COULD CALL ME BACK BUT NO ONE HAS. I LEFT A MESSAGE TELLING THEM I WANTED TO CANCEL MY ACCOUNT LAST MONTH BUT THEY HAVE CHARGED ME AGAIN AND NOT REFUNDED MY MONEY. THEY TOOK MONEY OUT OF MY ACCOUNT AGAIN THIS MONTH AND I STILL CAN NOT REACH ANYONE. I HAVE CALLED ALL MORNING - KEEPING IN MIND THAT THEY ARE 3 HOURS BEHIND ME AND LEFT A MESSAGE BUT STILL NO ONE HAS CALLED ME BACK. I SENT THEM AN EMAIL STATING THAT I WANTED TO CANCEL AND GET A REFUND AND I STILL HAVE NOT HEARD BACK THAT WAY EITHER.
