I got a new iPhone (that I pay for) today, and within 30 minutes of leaving her house I get a strange text from cool4cell.com. She calls me and literally yells and demands the PIN number. Eventually I give in and realize it says '$9.99 a month.' I unsubscribed immediately and asked her what she was thinking, and turns out she signed me up for some spam pop-up claiming to be giving away iPads. I signed up for the do not call list, anything else I can/should do?
