Best Replacement Backflow Devices in Chandler AZ

I had them out to repair a toilet flange. Took 15 minutes and they charged me $200 for labor, though I had to calculate that myself because they didn't separate materials and labor on the bill. I thought they were charging me so much for labor because they were going to screw the new flange to the floor and there were no existing holes, but they didn't so now its just going to break again in a couple years

They didn’t show up when scheduled. No calls from the business to explain what was going on after waiting 4 hours for the appointment and find out that supposedly the guy never showed up for work. They seem more concerned about the new sales then servicing existing customers.
