Claim

I was called and offered an extended car warranty of which I accepted. Now that I'm making claim I am asked of service history of the car. 30k service history is missing and don't know why cause I bought the car @ 32k on the clock. Now the car has 127k reading. Can they really justify that the 30k missing service history be the reason for the damaged clutch kit because they say they won't pay for it. I mean the car has been fully serviced afterwards, six times
