From the article:
I noticed that my Comcast bill this month was about $25 more than usual. Upon reading the billing details, I saw a strange $25 "return item" fee. I called, and the Comcast billing representative explained that they had accidentally double-billed ALL customers who use e-billing.
I heard a woman complaining on the elevator at work today that "the cable company" (I didn't ask) charged her account twice. Shoulda guessed who it was.
