Pristine Derma Care Vitalia Derma Nothing is free! Hollywood, FL Internet

I ordered my FREE sample of Pristine Derma Care from an ad on the Internet and paid $4.99 shipping using my credit card. It arrived in a box with no packing slip, no paperwork whatsoever. I then received an email saying I would soon be receiving my next shipment for over $80. When I checked my credit card statement it was being charged in pounds which is well over $80. I called the company and said I didn't want this and was told it would be cancelled. I also called my credit card company and had the charge disputed which was granted in my favor. The packages arrived  anyway when I wasn't home , I  called company again and they said to keep products. Since then I have been harassed by phone and email by a company called Rightsignature.com, 7414 Hollister Ave. Goleta, Ca 93117 that I have to sign a document to reverse the dispute to pay these people. This company has called me every day until I stopped answering the phone. I contacted my credit cand company and they'be never heard of anything like this and advised me not to sign anything as the dispute was granted in my favor. Nothing is free!
