Amir and Sanchez Neutraceuticals Dermatal Charges for Products not ordered Tuscon, Arizona

I ordered a free sample of their  skin cream, Dermatol, and was supposed to pay $4.95 for shipping only. No where did I see anything about being signed up for more products, as I have seen onother websites for supposedly "free" samples.
The product broke out my skin and was outdated by the date on the bottom. Several weeks later, another jar arrives - also outdated -  with no invoice, just the jar in an envelope.
My credit card was billed $94!
When the 2nd jar arrived, I looked for some way to contact the company and found nothing! I finally tried e-mailing through another website, but received no reply.
I am currently challenging this charge through my creidt card company.
