Interesting addendum to E-Harmony

I guess this past weekend was free for singles on all dating sites. So, I had made a profile for True.com but never used it. I don't know how it happened at all, but my credit card was charged for $50 to true.com... I may have put my info in previously and then decided I wasn't going to pay for it - but I DEFINITELY remember not clicking OKAY TO CHARGE ME MONEY!
