American Water Resources Reported a leak in my sewer line. They said it was not a clog or a blockage so it wasn't covered Alton Nationwide

Called American Water Resources and reported I had a leak in my sewer line.  They told me one of there reps. would contact me.  Two days later I received the call.  They told me that sewer line leaks were not covered.  I told them the leak was due to a clog in the exterior sewer line.  They said that I reported a leak and not a clog so it was not covered.  I said what if the exterior sewer line is collapsed.  She said it was not covered.  Only thing that is covered is clogs.  This service does not cover anything.  Bad service do not get it.
