Transunion Deceptive enrollment, non-return of membership fee Internet

Signed up for a $1 credit report even though credit reports should be free.  They did not make it clear that I would be enrolled in a credit monitoring service.  Was charged for membership fee.  When I cancelled several days into the current month, they would not refund the credit charge, even for the remaining unused month.  Since I did not notice the enrollment in a full credit monitoring service, I consider the practice to be deceptive.  I hope that consumer protection agencies on the federal and state levels should look into this, because it may violate existing regulations.  Attorneys should look into this because if others may have similar experiences.
