You heard it first here, calling bullshit.
Consumerist articles tend to be on the rather self serving side. Beside the fact that Comcast couldn't give two shits about someone, let alone enough to actively seek out folks and find out where they work. As was stated in the article, why would Comcast single out this individual when they get calls every single day of "I'm a lawyer at a big firm" or "I'm the CEO of important company".
Smells like bullshit to me.
