Please, I could really use some help. Was taking my money back the right course of action? Should I try to avoid them in any way I can, or approach them to try to get it canceled? I apologize if the fact that me using false info on some things on the net puts you off. I have a sort of paranoia thing going on about the internet.. and this is the reason why. =/ Please.. I'm losing sleep over this. Help!

Hey there guys. I, like most of you, are victim to usenext. I have managed to get back my money though. When I signed up to usenext, I was merely looking for a download my father was trying to find. I saw an ad on a site for this, and figured "hey, I may as well, right? its a trial after all". Now being all click happy, I briefly skimmed over the details, not noticing all the catches, and continued on thinking they'd let me know before-hand that they were going to charge me. I was charged.. not even full way through the trial. Well, they attempted to. I saw the charge on paypal and immediately requested a return to me AND attempted to cancel my account on usenext. Paypal saw it my way and set it to return status. A few days later, on pay day.. I was billed for $137... and usenext re-opened my account JUST TO BILL ME. Being payed weekly at $10 an hour, I need this money for bills. I called paypal back.. and they said they were already on it. Today, I got my money back. But.. even as I'm typing this, my account for usenext is still active, and I'm afraid to go in to try to cancel it again. They do not have my address, though. It was a fake. Nor does paypal. What I'm wondering is.. should I be afraid? Should I make any preparations for a legal battle? What should I do? I'm lost, and really need some guidance. They have yet to send me an email.. Edit - Correction.. paypal has all my info. Should I try to change it?
