Pure Diet Health I ordered their product to try, then they say since I did not cancel, they had the right to bill me. Utah

I ordered two products from them at a low price, received them, read the whole web site they had associated with these products and no where did it say I was joining a monthly club or needed to cancel to not be charged. When they started charging my credit card, I could not even get their number from their to see why I was recieivng thie procduct, not bill inside with a number on invoice. Then after many charges I finaly get a box with a Thank you card and a phone number. I called this number and they say since they sent me Emails and I did not cancel I am responsible for the cost. I let them know I received no Emails and asked them to forward the agreement where they say I signed and the last person said she would. I asked for then to transfer me to someone up the chain of command and she said they would have to calll me back. This is a major scam and I intend to fight them.
