Brio Day And Night Serum DAR Waterfront & Associates I was charge for a FREE trial product and now turned over for collection of money I don't owe Sherman Oaks California

Advertised a free trial sample.  They got my credit card number for the shipping charges.  After I received the product, they charged the full amount for the product to my card.  I called the card first.  They said I had authorized the purchase so they would not take the charge off my card.  I then called Brio, they said the free trial was only until I decided to keep the product.  That I should return it for a refund within a certain time period.  This time period had already expired.  I told them to cancel the "subscription", which I apparently had signed up for, and to not send any more products or charge my card again.  I also cancelled my card and got a new account number.  That was months ago.  I saw that some of my facebook friends had been ripped off the same way.  I figured they were advertising the free offer and then ripping people off for $74.12 for the first payment before the person cancelled the subscription.  Some people probably got ripped off for more than one shipment before they realized what had happened.  I thought that was the end of it until I received in the mail, yesterday, months later, a notice of an attempt to collect a past due balance from DAR Waterfront & Associates.  They want me to pay $74.12 again.  I imagine some people will just pay this because of the intimidation factor, so they are making money again from the initial ripoff.  I am not paying them anything more and I am putting it out far and wide so that others who have been ripped off will know about it.  I never used their products.  The first shipment of the free sample that I was charged for is sitting in my bathroom cabinet.
