Best Mechanical Piping in Glendale AZ

I have a very busy schedule. I gave them my number as a secondary and a primary number for the person who will actually be at the home at the time of the service. Had an appointment arrival time of 10am-12pm. Started calling the office at 12:10 because we hadn't received any info and no one had arrived. Were told someone would be arriving within an hour. Got a call to my number at 1:45pm while I was at work telling me they were 5 minutes out. The lack of communication and the inability to follow instructions just felt very unprofessional. What's the point of having an appointment if they can't hold to it or at least communicate if they are running late. It just felt more stressful than it had to be.
