GPM Merchandise Direct Charged my debit card with no purchase from me. Internet, New York

I check my bank account everyday and on Sunday April 10th,2011, I happened to see a charge from GPM Merchandise Direct. I asked my husband what was that charge for and he did order anything from them neither have I. I called the 1-800-366-6937 number and their working hours are from 8:30am-10am EST,  what kind of company is only opened for an hour and a half? The kind that steals your money and runs. The charge for this is suppose to come out of my account on April 11,2011 but if I get to the bank in time I will stop it. New York is not that far away and if I can find an address these people will have to deal with me in person and I don't think they will like that too much when I bring the law with me.
