AHS (American Home Shield) Four plumbers all want to sell me services I don't need or they won't repair my house. Different issues Internet

I have had three different plumbing issues.   Each plumber who comes to my house says its not covered and I need to buy other items costing hundreds to thousands of dollars.   When I get a second opinion for the same leak, it is not covered for another reasons per the next plumber.  I was a trained plumber.  These guys are just trying to sell me items I don't need and convince me and AHS it is not covered because AHS pays them so little to do the work.  AHS is a big scam.    The plumbers are criminals trying to wrip off the home owner.  If you don't know about plumbing watch out.   Thieves, thieves and thieves!  Don't get a home warranty.    Just get the trade you need, when you need the person.
