Global Fulfillment services Luminant Skin Charged $93.95 to my credit card without authorization. They stated I had an "Account" Clearwater Florida

I requested a "free " sample of Luminant Skin cream, but had to pay $4.95 in shippping, which I did approve. Fourteen days later, I see a charge for $93.95 on my credit card. I called and was told taht when I ordered the free sample I had also comitted to an order unless I called and declined. However, the printed receipt with the shipping charge did not have a phone or e-mail - if that is the case and looking up in the website under Luminant, there is no direct "contact us". I have called and sent e-maile to have this amount credited and an address to return the sample, which to date I have not opened, but was met with resistance until I said it was my legal right. I was given the address: Global Fulfillment, PO Box 10841, Clearwater, FL 33757. When I lloked up the address, the information on the various scams came up. I have written to my credit card company to dispute the charge and have it credited. However, I hope that by reporting this, these people can be stopped from stealing. Thank you. Marg
