Home Warranty of America [HWA] review: Services not rendered

I have attempted to use this company for service twice and was denied service. When AC was not working in August, they wanted me to wait 2 weeks for service. I talked with them about finding someone on my own, then they promised a partial refund that I never got. Now my heat is out in January, they sent someone out the next day, that refused to put the covered freon but still wanted his fee. He then texted me and wanted me to hire him outside of the warranty and pay him over $7,000. HWA quickly canceled the work order so that I again could not be refunded. I had a friend who referred me to someone outside of using warranty and had heat the same day for $360. So I am out over $1000.to sign on and very unhappy.
