Complaint Review: Greatfunonline.com

I recently bought a ticket on priceline.com, they offer me a $25 dollar rebate which i gladly accepted. A month after greatfunonline.com withdrew $11.99 out of my bank account without my knowledge. My bank account was later overdraft and i had to pay my bank and extra $35. I was so anger because i had no clue, about this transaction and i never heard of this site before then. I later called there customer service and they had all my information , like my name my address etc. This made me irritated because the told me i sign up for this site. I am not stupid, i would not give out my personal information to someone and a website an don't know have. I believe they got my information form price line.com but how is this possible?
