Can this happen to me? Please read.?

I went to a site via email, and started chatting with this girl. She wanted me to go to her site and vote her as the top model. She gave me her site, I went to her site. She told me to make an account, when I was almost done, she told me that I had to pay for it. I told her I didn't have the money to pay for it and then I left. A few days later she sent me a message over Yahoo! mail, saying that that site was going to charge my credit card 69.95 a day, until a completed my account. She also said that the site had my IP address from my computer. My real question is, what card are they going to charge it to? I used a iTunes gift card. and I gave a fake address? Can they still spam my house and fake credit card with stuff? or are my parents going to get charged 69.95 a day for a small mistake that I made. Thanks alot for reading all this. I know its alot to read. Thanks again,
