This could have been hidden in some of the paperwork you signed. Unfortunately this kind of thing is all too common with certain stores attaching free trials that turn paid automatically. Additionally it might be out of the hands of Best Buy at this point too. Often times the point of sale just acts as a broker to pass along your information to another company that's offering the service. My suggestion would be to contact your credit card company and report the charges as fraudulent or not authorized. Follow the credit card company dispute process. Get a new card number issued to you and your problem is fixed. Additionally the credit card company will pursue this with whoever is issuing the charges and may possibly trace it back to a broader case is fraud.
