Another thing to avoid them "hacking" your online account, is ignore the slew of scams going around for specifically VZW customers that tell you (via text message, call or email) you're eligible for some type of bill credit or promotion. It then points you to a website that looks like the real thing only it asks for your billing password on the very front page in the log in area (something the real website doesn't do). If you get taken in by these scams, a hacking of your account is almost guaranteed to result.
