It didn't appear that the Case had our last communication info which was an e-mail reply to Sage, so @JeffSchwenk you may be right that they just closed it out. Tech didn't have any info about the automated system issue with the dead air. I even tried it multiple times, and from different phones in case it wasn't correctly interpreting my entry. But we know the Case # was correct. And when I got the dead air, I did try waiting a few minutes for something to happen, like a transfer to a live person or some other prompt, but that didn't happen.
