Best Smoke/Co Detectors in Phoenix AZ

I waited all day today which their window is from 8-4pm. I had disbatch team call 3 times and now it it 4pm and when they called to tell me unfortunatly their tech is running behind and unable to do the job. I needed a tub removed and he stated at 4pm I will have to call my manager to see if we even are able to do that! Why wasnt this called and discussed weeks prior when the appointment was made. I will be going Ben franklin plumbing for this job and will not be using or recommending for future jobs.
