A lot of customers hang up.
Cellphones drop calls midway through important sentences. Modems that also handle phone connections fail while we're working on the internet connection, and so the call drops too. Or, sometimes, we reset the modem without checking to make sure the customer's on a different phone. Whoops. And sometimes our phones drop calls mysteriously- they're an elaborate software mishmosh of different programs that work together more or less and sometimes get erratic. Or we screw up transfers, so that customers get dropped that way.
But sometimes customers just hang up. Maybe they fixed it themselves; maybe they just got sick of being on the phone.
The customer I just didn't talk to, for instance, was on hold about 45 seconds, but hung up before the transfer could complete. I tried to call back and couldn't get through. So I don't know what she wanted.
I'll never know.
