HomeServe USA Repair Management Corp The warranty company Homeserve refuses to fix my waterservice line. norwalk Connecticut

I took out a warranty with Homeserve USA introduce to me by American Eletric Power.  This warranty stated that homeowners are responsible for repairing or replacing the line.  My waterline broke June 4, 2016.  I called HomeServe on that day, a plumber came out.  His finding was the issue is inside of the house which is Interior.  I am not covered for interior only Exterior.   I was not made aware of Interior waterline service from this company until the line broke.  I call the city to shut the water off from the street on June 6, 2016 the last day that I have had running water.  The city came out on August 2, 2016 their finding was the leak is Exterior.  On August 12, 2016 a plumber from HomeServe contracting came out again.  He stated the leak is in Interior.  I have came to the conclusion that this company does want to fix my water.  How was I suppose to know that my home was builted on part of the waterline.  This is what HomeServe is telling me.  I never recieved anything from HomeServe stating that I needed an Interior warranty.  Please help ME.  I am 68 years of age.  I have been lifting water cooler jugs 8 of them per day and paying people for water and to transport it to me.
