I bought a new Play 5 gen 2 in December 2019 with the idea that if I loved it, I would buy a second right away—I wanted stereo. I did love it and but almost immediately Sonos discontinued the model I had just bought, and the new 5 was designed not to pair with the Play 5 gen 2. I called and I wrote Sonos asking to return the unit so I could upgrade. They offered me a 15% credit instead. Sonos wouldn’t stand behind their sale and I was stuck. 

Then this week, two and a half years later I received a survey from Sonos. I told them what had happened and they set up a call. They never called. So I called them and after 40 minutes on hold they escalated the issue. All for naught, they just offered the 15% again. Sonos wasted my time and money.
