grants 360 .com - Grants 360 was 24 hr trial, only rec;d disc nothing else. How do I return? Internet

I was researching federal grants on-line and this company --Grants 360-- was a company that had 4 stars as its rating for information needed.  It listed a 24 hr trial period and then your credit card would be billed.  Initially all you had to pay was $1.95 S & H fee.  When I rec'd the information, all I received was a disc with no paper work or place to return it.  The mailer had a 12/9/09 postmark.  I rec'd it on 12/14/09.  I reviewed it immediately, found it wasn't for me and tried to find out where to return it.  I could not find out anything.   No way was this a kit. It was a disc mailer without a return address.  Nothing else.  I feel this was a fraud due to the way it was advertised and what I rec'd!!!
