What happened to all of us is this -- We clicked on a free trial but didn't read the fine print in the "Terms and Conditions" - we are all smart people, but we are all vulnerable because we like to think that if it's got the CNN, NBC, Google, etc logo - then it must be legit. And really, it is not fair that they use the logos but the fine print warned us that they were not affiliated with those companies.
When we gave our credit card number for the free trial of the "work at home" information, we also gave permission to set us up for other accounts - trial periods - with FSBO (For Sale By Owner) EZ-Books, Home Business Advantage, Universal Buying Club - and on and on -- all there in the fine print... when the 3-day, 9-day, 14-day etc.. trials end - then the real pain comes - $34.95, $114.97, $77.88. To stop it, unfortuantely, you have to call the bank and cancel your card. Otherwise, try calling one of the various 888 or 877 numbers and I am certain you will have a very very bad connection.
I know, I know... if it sounds too good to be true... - I'm sorry it happened to you all, it happens to the best of us. The good news is that if you used a VISA-logo card to sign up - even if it was by accident -- VISA has a product guarantee program... Check with the issuer of your card and file a claim against XM Brands (or whomever got your money)
Also file a report at the FBI.gov website as well as your State's Consumer Protection Agency.
