Scam and frauds

I paid $1 for a 7-Day free trial. It was for a credit report. 3 days ago I called them and cancelled the 7-Day trial and they gave me a confirmation number for cancellation. Then this morning I realized they charged me today $69.90!!!! I am going to my bank today and filing it with them. If I were to do this to someone's account I would go to jail for theft. So I intend on charging them for the same thing. I have a confirmation number in hand from them.
