Ivory White whiteningfast.com - this company is horrible, they scam people. They illegaly charged $94 on my credit card. HELP! Internet

This company offered a free whitening pen (this was an internet ad) and asked for credit card to pay the shipping of this free pen, however a week later they charged my credit card $94 for a "TRIAL" package which I never asked for. They are horrible, they hang up on me when I called and did not want to give me a refund or at least talk to me about options. I wrote emails and the answer was the same: rude and definite that I will not get my money back ...ever! 

Also the product that they send me does not have information on manufacturer. I don't now who made it and I don't think is safe because it contains 35% peroxide. They need to be stopped. They victimize people every day!!! I could not get real information on who they are.  I spoke to 2 people and they did not want to disclose their names or the contact person from customer service. Please Help!!
