Claim refusal based on a technicality

I bought an extended warranty from Volkswagen which is apparently underwritten by Bidvest. My car has been repaired numerous times under my manufacturers warranty but I am now in my extended warranty period. My service records show that I am 4000km over my service but my car itself (on the dashboard - I have a photo) shows that my next service is not due yet. I would NEVER EVER have pushed my car that far over its service intervals if I knew that was the case. VW admitted that they reset my dashboard by mistake. They also confirmed the break down is mechanical and would not have been picked up or prevented through a service (and a report to this effect has been provided to Bidvest by VW). Bidvest flately refused the claim even though they admit that I am not at fault . Well done Bidvest on getting off on a technicality - I'll be sure to spread the word and I suppose I'll see you at the ombudsman...
