Complaint Review: DAR Waterfront & Associates

I ordered a free sample of eye cream from an online company and all I paid was the shipping.  Several weeks after I received I got a bill for $99 for a monthly shipment of more eye cream.  I called the company and they explained that when I ordered the free sample I also signed up for monthly delivery.  I told them that is not what I wanted and they should cancel any subscription they had for me.  They said that since the free sample was really the regular store size I would have to return it to have the charges stopped.  I immediately sent it back and also called my credit union requesting the charge not be paid.  They sent me a letter saying thet would dispute the charge and until it was resolved it would remain on my bill and I should not pay it.  Eventually the Credit Union notified me that the dispute was resolved in my favor and the charge was removed.  Now, about a year later I get this letter saying I owe $99.01 and it was turned over to a collection agency...DAR Waterfront & Associates.  I prepared a letter to reply to them but then decided to search their name on the internet and landed on your website and see that the whole thing looks like a scam.  I am not going to reply.
