Youth Renu Signed me up for auto-delivery when that wasn't even a choice on the website. no idea - online Internet

I clicked on an ad for Youth Renu when I was at another website.  It took me to a page where I could order a trail size for $4.95.  There was absolutely nothing on the website about signing up for auto delivery.  I would not have made the purchase if there was.  I received the product and then received an e-mail 2 weeks later saying that my auto dlievery shipped.  I contacted them using the information in the mail and was greeted by a very rude customer service person when I asked why I was being shipped another jar of the product.  He insisted that I had approved auto deliver.  I told him I had not and would be returning the product.  He adamantly said there were no returns since I approved auto delivery and I would be charged $94. for the jar they shipped.  I told him to cancel my order and he said he did and I received an e-mail confirmation.  That was a month ago and I haven't heard from them since.  When I search the web for their website, at the time I did find one at youthrenu.com that did have a disclaimer about auto delivery.  But that is not the site that I ordered from.  When I search for them today that site doesn't exist. These people are scamming people $90. at a time.  I'm just hoping I don't get more charges from them and am hoping they can be stopped.
