My question involves a consumer law issue in the State of:

First off, I apologize if this is the wrong forum...

I recently got an email from a site I visited yesterday. I'll come right out and say it was an adult website, though, it is rather irrelevant to the situation.

This is the source of the problem:

I entered my e-mail and such, and Gained access to the mediocre website. This morning, I checked my email, and I got a message from a company called "United Payment Limited" Billing me for 59 Euros and it has to be payed within 7 days or some jargon like that. I am kinda freaking out at the moment, because I entered no credit information, but they have my e-mail and ip address. Am I really gonna have to pay this? I mean, I saw no charges or anything upon joining at all, and now they throw this at me.

Help me out?

-Thanks
