Where Do We Start?

Contacted AHS on 719/17-Wednesday for a service request to diagnose an AC/furnace problem. They identified a technician but they couldn't come out until 7/25/17. We canceled and requested another tech who was assigned, scheduled a 10:00am on 7/21/17 but didn't show until 1:00pm. Diagnosed problem quickly and stated he could get part from Carrier near my home but had to follow protocol and let AHS purchase, contact him again and send him back out...stated on average he's seen this take 2 weeks. I reluctantly called AHS as prior calls, outside of initial servce request call, took on average 30 minutes or longer and still no answer. I used the live chat function and requested them to reach out to tech and retrieve his report, as tech's promptness was already in question. Today there's no chat function on website??? Called and was on hold for 30 minutes before being disconnected. I called corporate and left a message 901-597-8000 requesting a call...we'll see. This is the second service request we've made with AHS since opening a contract with them about a year ago...and the first only got taken care of because we communicated directly with a manager...ONCE we insisted we be put in contact with one. I posted on Twitter 7/19/17 and received a message stating a social media rep would be in contact but haven't heard from them either. And what is a social media rep going to do?? Extremely frustrating dealing with AHS.
