first gold plus credit card fraud Internet

Same as previous post.  I saw a charge on my checking account but when you try and call, there is no answer and the street address appears to be an abondoned home or a parking lot.  I have written to request a refund but not response. I have alerted my bank to these scam artists.  I have called at all times of the day.  I am confident my written correspondence will come back undelivered. The concern is how they got my checking account.  I don't do business with these kinds of shopping clubs or whatever these criminals call themselves.
