Advanced marketing group so called job,nothing like advertized Internet

My goal was to find an envelope stuffing passtime. The ad was in the paper that I picked up at the P.O.and seemed to the point yet honest; I felt confident that this was the real deal, I was beside myself. I signed up last Monday or Tuesday (today is febuary 23rd) and the ad said usually charged $37 and was having a sale for $22. I gave him my card number and now I not only want my money back ; I also want this person to not have access to anymore of my money. This person was only authorized one withdrawl, and that was for the first and last withdrawl of $22. I am very interested in any advise or sugestions for a person in my positionand would greatly appreciate any advice and sugestions. This Obviously Was A  Mistake.
