Renue Derma Deducted money from my account before the trial period was up. Internet

I ordered the $4 trial of Renue Derma on 10/18/2015.  I called then on 10/28/2015 to cancel because it wasn't what I thought I was ordering.  When I went to pay my monthly credit card payment I noticed they charged my credit card $94.57.  First, when I called them to cancel the first time this woman kept trying to offer me some other nonsense also asking me to give it just 3 more days (which would've put me past the trial period) and tried to insist on talking over me, which eventually failed.  When I called them yesterday regarding the deduction from my credit card, she tried to tell me that the trial period had cancelled.  After chatting a bunch of crap, offering first a 50% refund, then a 75% refund, I told her I would contact the Better Business Bureau, she then told me I would get a 100% refund and waited on the line with her until I received the email.  Prior to the phone call I did dispute the claim with my credit card company who issued me a temporary credit, but this was before I received the 100% refund email from Renue Derma.  Don't give up when asking for your refund.  They are absolute con artists to the core who I would prefer to deal face-to-face, I would've wasted less time and would have the 100% refund immediately, bypassing the 50% and 75% offer.  Thieves...that's all they are.
