Wuyi Tea the company sent me product, even though I cancelled my order at the time of ordering it Ontario California

I got this email and was just checking it out on, next thing When I saw how much they wanted for the tea, I pressed the cancel button, they still shipped my free trial, and I just got a new shipment, no bill, there is literature that says to call, but no phone number. I do not want this product, I don't know how to find out how to send it back, I do not want my credit card or my bank account charged for this product, I pressed the cancel button on the site and it was just ignored.
What can I do?
