WC Budget Savers Telephone Scam Billed my credit card which I did not authorize Minnetonka, Minnesota

I received a phone call from WC Budget Savers wanting me to take some kind of coupons and I told him I was not interested.  The next day I received another call offering me coupons again.  I said I was not interested in anything he was offering.  I watched my bank account online and noticed a $1 charge from WC Budget Savers MN with a phone number 800-475-1942.  I called them and asked them what they were doing going into my bank account.  The lady said I subscribed to some kind of program.  I told her I did not do so and to Cancel this and stay out of my bank account.  She said she would cancel but I am cancelling my debit card to be sure they can't use it again.  These people should be investigated by the Attorney General for this fraud.
