About a week ago, I sent two speakers for replacement. Only one had a problem with the Wi-Fi, but since I was using them as a stereo pair, the representative told me to send both. They received the first one (the one with the Wi-Fi card issue or something like that) on Wednesday, 4/25, and sent the replacement the same day. I got the notification that they received the second speaker on the same day, 4/25, a few hours later. It's been a week, and they haven't even sent me the shipping number for its replacement. According to their email, I was supposed to receive the replacement 1 to 5 days after they received my speaker. I've contacted them multiple times, and all they tell me is that they've escalated it to the returns area, but that doesn't help me. The first time they escalated it was days ago, and I still haven't received any follow-up email.
It's quite frustrating because I've read stories from other people here, and it seems that when this happens with SONOS, it can take months to resolve. It's even more frustrating because I didn't plan on sending this particular speaker in; everything was working fine, I did it because they requested it.
