Ringtone.com / Charged $9.99 without knowing!
Thought we were downloading a single ring tone and somehow got signed up for music triva text messages for $9.99 a month. Took me 4 months to notice and get if off my bill. Ringtone.com would not refund me even when their own records showed we only got 1 text message in the 4 months. Watch out and read the fine print if use these guys.
