M-Sure does not want to pay!

Very very disappointed in the service. My wifes water bottle failed and caused the abs pump to fail. Now they say I'm only covered for mechanical or electrical failure on the pump. But if the primary failure was the bottle surely secondary damages should also be covered??? By saying this to me do they then cover valve damage caused by an failed cambelt?? Its ridiculous that they only want to cover a 1.2k part out of the 32k quote. I'd be more than happy if they just cover the 20k as per signed agreement. Very very sad to say that a 2 -year 13k warranty absolutely means nothing!!! This is my firts claim in 20 months.
