Bill Leary Air Conditioning & Heating

I had a guy from Bill Leary come by and do some work on my AC and put the Nest thing on my wife's phone. One of their guys put the Nest in my daycare half a year ago but he's gone now. A new guy came on June 21st and he couldn't get the app on the phone (the old guy did it in 5 minutes). While he was messing with it, he did something to the thermostat and it stopped working. The next day, the AC wasn't working at the daycare. I called Bill Leary to come fix it since they messed it up. This is a daycare with little kids, you know? But they said they're canceling my contract and won't work with me no more. That's messed up. They broke it and won't even fix it.
