I put my info in with Blockbuster online and they had some survey where they ended up with my info and charged my checking account $49.95 without me wanting or needing there product. I have sent several messagess to them without results? They say that since I took the servey I Autherized them to deduct this money from my account?

I had 5 different companies do the same thing but they all returned my money. This charge costed me a NF charge of $31.00 because I did not have the money to puchase this and did not know what was going on until it was to late?
