American Home Shield [AHS] review: We went through the hottest part of summer with no air conditioning.

We have been without air conditioning since August 26th of this year. We have had several visits from All Zone in Madera California but still nothing. We have called American Home Sheild customer service line so many times we know the number by heart but nothing. We get apologies and canned responses which we also know by heart. We received an email yesterday at 6:33 pm from American Home Shield stating that we would hear from All Zone regarding the part that has been available for them to pick up since October 16 and as of now no phone call from them. We called American Home Shield customer service number again and now we are told to wait until Monday evening. I have no faith that this call will come. We have also tried to call the contractor at number given on the dispatch emails from American Home Shield but no answer. We have asked to speak with an American Home Shield supervisor many times, but we are told they are not available. We have had 3 different dispatch numbers for this same issue because customer service keeps telling us that the contractor is closing the tickets. We are beyond frustrated. Can you help in getting this resolved?
