Youth Renu falsely enrolled to monthly charging (stealing) monetary fee for product, to scam me Internet

On April 17, 2017 I responded to and internet offer of free sample for puffy eye reducer cream from Youth Renu with a $4.97 charge for shipping. I recevied the product and started using it. It did not perform as advertised and did not reduce the puffiness. 

On May 1, 2017 while reviewing  my online bank statement I found a pending charge for $89.97 from Youth Renu.  I immediately called the number on the statement for the company of 888-853-3479.  Spoke with a woman named Candice. I told her I did not order any more of the product and certainly did not authorize any further charges to my credit card.  She told me that I had enrolled to receive the cream and agreed to the monthly charge when I ordered the sample. I told her no I did not, and she informed me that I did not respond within the timeframe to decline that was supposedly on the website when I ordered the sample.

After going back and forth disagreeing on the charge, she told me that she could cancel my enrollment and refund only a 50% amount to my credit card. I releuctanly agreed to the 50% and was told I would receive an email within the week confirming that I canceled any further shipments and the 50% refunded would take a couple of weeks.

Needless to say I have not received any email confirmation as of this date nor recevied the 50% refund of the amount charged.
