Sounds like all you might have is a prayer to get this fixed unless you are willing to pursue a legal route. Curious: How old is your home? Sometimes "things" just don't seem fair but life is so short it is also sometimes best to just move on. Wish I could offer better advise but in this instance can't! I'm asking approx. age of your home to get an idea on how well the infrastructure might hold up. Of course, this could just be a "freak" one time thing.
