Encante Eye Cream I ordered what was supposed to be a free trial and if I didn't like the product I could call and cancel Internet

I ordered a "FREE" trial of some face cream that was being advertised by Christie Brinkely.  They charge a shipping and handling fee and if I didn't call within a certain time period, they would send a shipment monthly.  I called to cancel and the person said that they would take care of it but apparently they did not.  However, the credit card that I used to pay for the shipping and handling was expiring that month so when they tried to bill me, I guess it was rejected.  However,  I never received any notification of this or any kind of bills or invoices saying that I owed them anything, now did I receive any more product.  

Now, this past week,  I received a collection notice from a company called DAR WaterFront and Associates in Sherman Oaks, CA.  The letter states that I owe $197.72 for this "FREE" sample.  I am disputing the charge but don't know what my legal rights are.  I have no record of anything.  Only this collection letter.  The collection company says in the letter that you can go to darwaterfront.com/dispute but when I try to click on that it says it's not found.  It also has an address to send my dispute letter to so I'm hoping that's not a fake address.  This is really deceptive and fraudulent and these people should be charged with fraud.  If I had known that this stuff costs $197.72 there is no way that I would've ever clicked on this link or purchased this producti.  I don't even like pay more than $20 at my local drug store for face cream so it would not be something I would ever do if I knew the hidden cost.
