When a Greenwich teenager went online and bought a video game with a debit card, he also unwittingly signed up for a membership in a discount program which meant an automatic $12 monthly charge to his card. The teen’s mother later noticed the ongoing charges, and the 2009 incident led to lengthy, ongoing federal litigation that included claims of fraud, unfair trade practices, unjust enrichment and negligent misrepresentation.

The 2010 lawsuit involves a Stamford-based company, the Affinion Group Inc., which has been the target of similar accusations in the past and two years ago agreed to a multi-million dollar settlement with Connecticut authorities.
