cellan they keep sending me products that I dont want and charging my account I have tried to contact them but to no aviol and there is no email address to get them to cancel my order Linlithicow, United Kingdom

I took the opportunity to try this product on a free trial  after waiting a month for the free trial to arrive in the mail. Then a few weeks later without my knowledge my bank account was debited $79.42c and then I was recieving emails telling me that I needed to contact customer service as my bank account was unable to be accessed to take another $76.. out but then when I had money in the account it was debited okay i thought obviously I havent seen that on the invoice so I reread the information and no where does it say that I would be charged this amount of money. Now today I have recieved another bottle of this product that i didnt order and I dont want, I have been trying to contact them to take the product back but to no avail.  So i gather in the next few days I will be charged for this product that i dont want and have no way of getting them to stop payment so I can return the product to the sender.
