info@car-registration.org misrepresented their website's purpose and gathered credit information for their unrelated "product" Texas

As I was attempting to renew my car registration online, I realized (too late) that the site I had just entered my credit card information on, was not a valid vehicle registration site, but it was a site that would send a pdf guide of "how to register your vehicle, etc.", for $19.99 instead. 

As soon as I realized this I called the number listed to cancel whatever it was I apparently just ordered.  The phone line's crackling made it hard to even hear anything and the option for "all other inquiries" press "0" was invalid; should have been a red flag right there...

Upon pressing some other number and actually contacting a representative, I informed her that I had made a mistake and wanted to cancel whatever guide it was that I ordered.  She then tried to keep my order by pulling in some other offer that included $100 in gas... but I insisted I did not want to be billed for  "anything".

When I said I wanted to cancel everything she said I would still be charged $2.99 for processing for some BS, and when I complained how their site was  misrepresenting people, she changed the subject asking me to see if I recieved their cancellation e-mail now; and clarified that their site states (albeit in small pring) that they are not affilitated with any state agencies.  And their "e-mail" had no company information on it at all, which was another red flag?? 

I'm now contacting my credit card company.
