I got one several months ago and if you read the letter that came with it, it says "we understand that because you didn't order it, you don't have to participate or send it back and you can consider it a free gift, but we hope that you will decide to participate". I got these notices that look like a bill, a couple of times. Just call and tell them that you are not going to send it back, and not to send anymore letters. It should take care of it.
