One word. Crazy. You are admitting this in the most respected forum? You wont earn any points for intelligence! EDIT: Im not trying to be bad... I would advise against filling out things!
I used to sign up for offers, but stopped because some of the companies gave me a hard time canceling. One example was I was canceling an AOL trial and spent over 40 minutes on the phone saying I didn't want it any longer and any other offers. The guy kept trying to get me to sign up for some spyware removal program even though I said I already knew how to do it manually.
If they don't give you a refund and they have a refund policy - chargeback. I'm amazed that some people have no idea what chargebacking is. Go call your credit card company and tell them that those companies are fraudulantaly charging your card. Your CC company will complete own them .
