RenuvaDerm Deptive Advertising Not sure Internet

I ordered a free trial of renuvaderm wrinkle serum and eye cream.  The add i clicked on said it was a free trial,you just pay for the S&H. When I recieved the product,there was no papers in the box. 2 weeks after the product was charged to credit card, I had 2 unautherized charges of $94.57 & $89.47. I called the 855.233.0006 or 855.581.1150 that were on my cc statement, I called and asked why I was charged? The lady said it was not free and I agreed to the terms.  I asked to speak to a supervisor and he was the coldest person on this earth.  He told me that I will not be billed any more. I told him I was not afraid of that since i would not let him bill another thing to my account.  I dont want anything more from this company and I would do what ever I can to inform people of this fraud. He said it said it on their website that I would be billed.  I told him i clicked on an add that brought me to a page that said it was free. He said that they have no other web page and I went to renuvaderskin.com.  I told him that I don't even have that website in my cookies.  He is a liar.  Anyhow, he said it is all legal. Under what law?  He didn't know. I then asked if it was so legal than why was there no invoice or instructions stating such in the box.  He said he would bring that up to his supervisor (he was probably not a supervisor).  Both people sounded like their only job was to rebuttle all the people that were scammed.
