Perfect Skin Unknown Unexpected continuing association with charges Internet

I was offered  a free sample of a face cream and eye cream from the manufacture for visiting a website. There was no indication that this was an ongoing subscription with a high price until after I received my first shipment. When I discovered that was the case I attempted to cancel my subscription twice through email. The email was rejected. My phone is out of commission at present and I am afraid that I will be charged over $130 if I cannot correct that situation in time or perhaps even if I can.
