Best Buy ILLEGAL withdrawal of funds from checking acct. jensen beach, Florida

Had anti-virus protection installed on new purchase of a laptop computer in 2010.  Did not authorize or sign to have any auto pay or access to bank accounts.

When checking the balance on my checking acct in Sept. 2012, discovered a 42.59 withdrawal for renewal of anti-virus protection.  Was not notified either by mail or email and had no knowledge of this until I discovered the withdrawal. 

I originally paid for the computer using by debit card. Called the Jensen Beach store, and was told they could not help me.  Gave me 1-888-BESTBUY to call.

After speaking to a representative for over 20 minutes, only to be told it would take 1-2 "billing cycles" to receive my refund (which is 30-60 days), I asked to speak to a supervisor.

I was on hold another 15 minutes.  The supervisor "Chiquita", came on the phone, and basically told me the same thing.

I told her that I was going to charge BestBuy interest to keep my money tied up for 30-60 days. She then hung up on me!

If this is not illegal, IT SHOULD BE.  I will NEVER buy anything from Best Buy again, and will tell everyone I know to steer clear of these ripoff Con Artists!
