Fiorvano Jewels Deceptive Subscription that will cost you about $100 Internet

On the first of December I had an offer to take a survey about the website mycokerewards.com and at the end I could get some jewelry for just $5.99 for S&H.  I took the survey, was offered a few options in jewelry and went with earrings that the website valued around $130.  I filled out the form and submitted it.  I got no confirmation email about it and I was charge $9.99 for shipping, not $5.99.  The earrings arrived looking not so great but for the price, I suppose they might have been worth it.  On the 18th of December my account was charged $98 by Fiorvano Jewels without any agreement from me.  I contacted them and they said that I needed to cancel my subscription to their service within 14 days of starting my subscription or I would be charged the full price of the earrings, which was $98 (lower than the $130 value on their site).  I never saw anything about a subscription.  I and my girlfriend were both staring at the page picking the prize and neither of us saw it.  I didn't cancel my subscription because I didn't know I had a subscription.  I'd made a one time payment for S&H and that the end of it to my understanding.  My bank is refuting the charge, but have warned me that the prospect of getting it refunded isn't good.
