The FTC finally clamped down on AT&T billing fraudulent charges for third party services, such as horoscopes, recipes, jokes, gossip, etc. Most of these companies tricked consumers into buying paid services that they thought were free, or just outright billed people who never ordered them in the first place (the latter happened to my dad).
Even if this didn't happen to you, you're eligible for money provided you had an AT&T cell phone sometime between January 1, 2009 and now.
You do not need to provide any documentation.
It is not clear how much you will get, and the money won't come for 9 or more months (LOL).
