So, I call Spectrum again and tell them what's what and the guy I'm talking to says the 29.99 IS a legit charge and that it was for the mobile phone, which is a separate department. Apparently I've gotten free mobile on whatever plan they put me on when I switched the phone service and that was for a year and now I have to pay. I was so irritated and asked why the first guy told me it wasn't a real charge, but obviously he couldn't speak for that guy.
