DC Sales LLC magazine scam Phoenix Arizona

A young woman knocked on my door, telling me she was selling magazine subscriptions to earn a trip to Italy. She said she was in a public speaking class and the girls were  competing against the boys. She explained the point system,  etc to me.

I foolishly agreed to help with her trip, wrote a check for $59 for a magazine and she went on her way. I thought it was strange, but had to fix dinner and didn't worry about it anymore. Finally _4_ days later I looked it up on the internet and landed on this page.

So right now I am trying to figure out what to do. It is past the 3 day cancellation time.....but if they are crooks, should it matter?  guess I will put a stop payment on the check.
