American Home Shield [AHS] review: Electric furnace. Started in October 2023

I have been dealing with getting this fixed for almost a year. Mountain heating and cool came out on October 21st 2023. After ordering 3 furnaces they put the 3rd one in. They could not seem to order one that would fit. This one has never worked it kept turning off. I tried to contact to come out to fix it. They never returned my calls. You tried reaching out to them and they never returned your calls or emails. After months of this you sent Mountain Heating out in June 2023. I was then told it was a electrical issue. I was told 2 wires were hitting each other. On September 9th 2023 INTEGRITY AIR HEATING & COOLING LLC came to my house. At this time I found out my furnace was to small to heat my house. After fixing that he found that the door to my furnace is hit the breaker causing it to turn off. He then got a hold of AHS and told them the problem. I was the assigned ILLUMINATE CONTRACTING LLC. When I was able to talk to this company the person was very rude to me asking what I thought he was going to do about it. He then said I need to start over with a new furnace but he could come out and look at it feeling he would not be able to fix it. I then called AHS three times stating what happened. I was told I would get a new vendor. I keep getting phone calls and emails saying ILLUMINATE CONTRACTING LLC will be coming out. I was told that the way I was treated was not ok yet I just talked to Mariane 655183 and was told this would be my vendor unless they could not do it. I have been with AHS about 20 years this is the worst treatment I have had. I would like to call my electrician and have them do the work. I burned out 2 space heaters trying to keep warm last year. I fear this year will be the same. Can you please help me
