Free Credit Score Illegally withdrew money from account after canceling service Internet

I signed up for there 7 day trial fr $1.99.  I canceled it within the 7 day period. I received and email from them confirming my cancellation.  5 months later I found out my account was overdrawn.  I couldn't figure out why, since I hadn't used it.  Upon speaking with the bank I found out that freecreditscore had been withdrawing the full fee from my account for months and as of the last transaction overdrew my account.  I call them and they weren't helpful at all.  I told them what they'd been doing was illegal.  I told them I contacted the Better Business Bureau which I had.  I also told them I was completely willing to contact my attorney about the situation.  I had proof of cancellation from them and proof of charges from them to my account post-cancellation.   Within several days the money was returned to my account and my bank waived the overdraft fee.  This company apparently doesn't mind committing felonies to obtain money.
