Complaint Review: American Home Shield

I purchased the top of the line home warranty coverage from American Home Shield.  I have had to make two seperate claims with this company (very small claims, but urgent in nature).  American Home Shield continually denies coverage even though their technicians tell them that items need to be replaced and it is clearly covered in the policy.  I have three thermostats that have been non-operational for over a month. Their contract clearly states that they are responsible for replacing these thermostats with "like" units.My thermostats are wifi/z-wave enabled to work on the smart home system.

I have been told by AHS contractors that even if the company can be convinced to replace them that they will be replaced with basic/bottom dollar thermostats, not similar units as speicifed in the contract. They have now tried toschedule 5 separate technicians to come take a look (booking more than a week out.  Most technicians AHS calls to have come out to my property aren't even qualified/capable of working on my HVAC system.  Contractors are not scheduled during appropriate times, they do not communicate, and when they do finally make anappointment, and report back to AHS that items need to be replaced, AHS does not allow them to do the work or fix the problem.  

It usually takes over an hour of waiting on hold to talk to someone by phone in their company, and I've waited over 10 days for a supervisor to call me back.  The supervisor offered no solutions other than booking a 6th technician to come out and corrobrate what the firs three have reported, that the thermostats need to be replaced.
