Does not function as advertised, a huge waste of my time

I bought a Sonos system six months ago from and installed by BestBuy for a second home which I am in about once a month for a couple of weeks.  I have become disgusted with the lack of consistency of the system.  At least once a month (once a trip) I spend anywhere from 15 minutes to well over an hour on the phone with service to resolve an issues of one or more units not playing or something else.  For the kind of money I spent, to have to spend that amount of time on a regular basis to keep the system functioning is beyond reprehensible.  On the off chance that somebody in charge at Sonos reads this, I will mention that I have already cost the company business by telling friends about my woes and advising them to purchase something that works as it is advertised.  Other complaints will never be addressed, like the portion of a minute of my life I lose every time I open the app on my phone from the time I tap on the icon until the app opens and becomes fully functional. This company wants to charge executive prices for its products and system and doesn’t seem to understand that people paying these prices consider their time precious and deeply resent that time that could be put to better use is spent nursing the system to stay functional.. Imagine how annoying it is to get a phone call and have to wait the better part of a minute for the app to allow you turn the volume down.  It’s a poorly designed system.  Further, the instructions and help articles were written assuming knowledge which few have and can be confusing at best and useless at worst.  Hey, Sonos, get your act together or risk going out of business..
