I own a retail store and there is another store right next to us that uses the same wifi. Overnight somebody unplugged the speaker I use and when I turned on the system this morning it automatically connected to the other store's system. I tried to add my play1 back to the program on my computer but all that did was add it to the other store's system. I tried calling sonos support and fb messaging them. Frustratingly, they have not responded to either of those attempts at getting support and it has been over an hour so here I am.
What I need:
Remove my speaker from the other store's system.
Get my system back up and running using my sonos registration and pandora/spotify/etc. logins instead of the other store's
If it helps I do have access to both store's systems.
