Taking money from my account without authorization

I have never ordered a game from this company. Yet for some reason they have taken money from my debit card account. I think that is so unlawful and there should be a stop to them riping people off. I had just received a new card in the mail and had only used it once to pay my cable bill. This is so wrong. I work hard for the money I get paid and here I am charged for something I had no part of.
