AuraVie deceptive advertising. unauthorized credit card charge Van Nuys California

When ordering from an alternate website an offer popped to select a free product, with a shipping and handling charge.  When the product arrived I used it and had a horrible reaction to it.  Thinking it was free and came with no strings attached I threw out the remaining product.

One month later I received a box in the mail with the same product and an invoice for $98.  Clearly I had been duped into a monthly program.  I called the company only to find I had been charged for the first shipment.  I have to send the product back to get the refund for the new shipment.  They offered a 35% refund on the first, followed by 50% and then 70%.

I finally gave up and accepted the 70% but they will only refund it if I send an email saying I will not dispute any charges.  

I do not recall seeing any information on being billed for the product if I decide to keep it, or that monthly shipments would be sent.  I believe that it is in the fine print, but I also believe that they hid this info very well in order to deceive me, the consumer.
