I signed up for Jamster (A ringtone service) All I did is put in my cell phone # and then it sent me a text with a PIN. I entered it on their website and it said I was activated. Then I saw it would cost me $9.99/month and immediately deactivated. Will I still be charged? My parents will be pissed if it does.... I know I am stupid, but what do I do? And I called them and they said the do not deal with minors since I am 16. WTF.
