I bought a new system with a SmartHub, delivered last week. The SmartHub is basically DOA, so I need a replacement. I called Monday, heard that I was #21 in the tech support queue. No problem, I requested a call-back and hung up. 48 hours later, no call back. I just called again, and this call was #9 in the queue. So, either they're not calling anybody back, or they've done fewer than 12 calls in the last 2 days. Any idea which it is?
