Best Doorbell Installation in Milwaukee WI

I had Martin over the first time to level out my backyard to install a pool.  I had recently broke my ankle and wasn't able to do much on my own. He helped me with so many other things while he was here; it was unbelievably helpful. Cleaned gutters, fixed a gate- and he ended up assembling and putting up the pool for me!
Fast forward 8 months -ankle still broke - I want to install a dog door for my upcoming surgery. He suggested a door, came out, installed it, and even followed up a few times to see how the dogs were liking it.
He's very reliable, cleans up after himself, and charges reasonable rates.
Bonus- he listens to good music while he works!

I'm sure the technicians do good work, but I didn't get that far. I called a week in advance and was told that they wouldn't be able to get someone to my house the next Monday at 8 am. I prefer the first slot, as a I work from home and have a hard time with arrival windows, since I generally have meetings during the day and may not always be available to let a technician in and talk them through the issue.  I received a confirmation call the Friday before and assumed we were all set.  I was never told that the technician would need to speak to me on the phone prior to them being dispatched to my home.  So when it was 5 minutes past 8 and no one had arrived I went to check my phone and noticed two missed calls.  When I returned the call to the office, I was told because I didn't answer my phone the technician was dispatched elsewhere.  When I asked if the customer service rep when that would be, her response was I don't know.  Obviously, I was counting on someone being at my home at 8am, so I was upset.  I told the rep that I was never told that the technician needed to speak to me and her response was we always tell you that they will call 15-20 minutes prior to their arrival.  I told her that I assumed that was just a courtesy, letting you know that they were on the way and that if I needed to speak to them in order for them to get sent to my house that I should have been informed of that.  The rep then responded very sarcastically I will dispatch the next technician that I have available and they will call 15-20 minutes before your arrival, AND YOU WILL NEED TO SPEAK WITH THEM PRIOR TO THEM BEING DISPATCHED.  Needless to say, I cancelled my appointment and will be getting my work done by a competitor.
