us search They slammed a subscription on my card culver city, California

I kept getting a local call that I didn't answer and they didn't leave a message. I used us search to do a reverse lookup. They offered two prices:$4.95 for just the lookup or .95 cents if I subscribed to their service. I chose the $4.95 option and that's what I was billed for, but somehow I ended up with a $14.95 a month subscription. They insisted that I must have entered my email address at the end of the session in some last minute pop-up that offers the subscription again. OK, then why didn't I end up getting billed the special subscription discount for the reverse lookup? Either way, I got scammed.
