Dotsure Extended Mechanical Warranty Rejected Claims

Dotsure has rejected 3 of my latest claims, where I have even escalated the initial 2 claims to their Dotsure Claims Customer Service (***) and they didn't even provide a response. My suspicion is that Dotsure is purposefully rejecting my claims with flimsy reasoning since they do not even bother with responding to the appeals directed to them, and this more evident on the latest claim where they are saying that I haven't been servicing my vehicle - even though the service history states that I have never skipped a service interval.

This is starting to look like a deliberate effort to frustrate me by taking me from pillar to post in effort to tire me from following up with my claims, and to also discourage me from further claiming in the future.
