National Motor Museum Mint NMMM Claims I ordered models of cars I did not order, and charged my credit card after I told them to stop using my number Wallingford , Connecticut

In December 2009, this company telephoned me; they knew somehow that I owned a truck.  They told me I was 'lucky' because they were sending me, for no charge, a gift of an "exquisitely crafted" Ford truck 1940's collector car.  They said they would also send "for my approval" two other cars of the same scale.  I must've agreed to buy something, because I gave them my credit card number, and told them I would buy only these, but no others, so not to send me any more in their series.  The set of two was around $32, which seemed reasonable.
After receiving the first set, other unauthorized sets were sent (and my credit card charged).  To date, I have returned two sets, asking for refunds (i.e. credit card credits), and I have told them by phone not to send any more, nor to make any more charges.  Today, several weeks after returning the last shipment, I received another one, indicating another $32 charge to my credit card.
I refused the package and will try to contact them by e-mail to give written instructions to "cease and desist" future shipments and charges.
Since I have communicated my instructions on several occasions, which they are blatantly ignoring, I am reporting them to alert you to their fraudulent and unscrupulous practices. 
Needless to say, they are causing me a tremendous inconvenience as well as interfering with my credit card activity.
