Stop the presses: We’re about to report a good customer service story. Well, for cable, anyway… When CableFAX’s very pregnant editor moved to her new Montgomery County, MD, home Sat, Comcast came knocking even before her boxes were unpacked, showing up ahead of the scheduled appointment time. AT&T, however, has proved to be a much more difficult nut to crack. Despite numerous phone calls and a deadline of last Fri for getting the service working, she still doesn’t have a dial tone. (Why, oh why, won’t Comcast launch VoIP yet?). The denouement came yesterday, when a tech failed to make an appointment. Thurs is now the next available slot for AT&T to mess things up. And managers couldn’t even take a complaint for the next 24-48 hours. (What’s the deal? Don’t they know I write for a cable trade?!?) It all makes us wonder how long it’ll take all those VoIP subs who fail to acknowledge e911 limitations to have a new phone service connected.
