In the end they covered the replacement of the lifters and camshaft.
Took a lot of persistence, but they reversed the denial.
So, you not only had to pay for this coverage, you also had to 'persist' PAST their denial to get them to reverse said denial.
In other words, they were counting on you to pay for what you signed for, then be all
'na, this money is ours not yours cuz we said so' but then you were all
'no it isn't, live up to the contract and cover the schidt you said you'd cover'
'na, we made up the rules, so we get to make up how we interpret the rules we made up'
...
I wonder, how much more persistence was required of you.
I would not be surprised if that much or more persistence was required of most of their 'clients'.
Glad you had the ENDURANCE to get what's yours.
