Precision Air and Heating Promise, On Time, Appointment, Warranty Chandler Arizona

HORRIBLE SERVICE!
Have had a call in since Sunday (5 days ago) and they company gave us a 5-9 block for yesterday. 
Around 5 yesterday they called to say it would be closer to 9.
9 comes and goes, no call and no ones shows up, so around 10pm we call and they have to page the on call guy (they only have 1 guy working at night) and he gets back to us around 10:30 saying he's still on a job for another few hours in Scottsdale (we are in Avondale!), so he could show up around 1am (maybe) told them this was not acceptable and he says he would call the office to have someone out in the morning.

We hear nothing from the office when they open, so when we call to ask on status they tell us there are NO OPEN SPOTS for us today since we "declined service" yesterday... apparently them overbooking and not making the 5-9 was my fault, basically we should have just accepted the 1am time frame that was so reasonable from the companies perspective (we have young children who are asleep so someone banging around in the attic from 1-3 am is not going to work when the time promised was 5-9pm).

Asked the manager to make us a priority today and she said that they will NOT do that and they can try and send someone but cant give a time and it might be yesterday all over again and the tech might show up after 9pm. ... WOW.

Mind you, the unit we have on our home is one from Precision Air that we bought new VERY recently and is still under warranty.
But I'm not a priority as a customer. Overbooking (ala UNITED AIRLINES) and missing appointments doesn't make a customer a priority, previous purchases from this company won't make you a priority, having the company hold you hostage for a week also doesn't make you a priority.

What I've learned, this company, just doesn't care about you.
