Maybe it is a scam
I have been receiving mail from a company called "Magazine Payment Servcices". Their mail looks like a normal invoice. Some are for magazine I currently have, such as Cruising World, but also for other magazines that I have never had. I think they are hoping that I would be dumb enough to think these are real bills, and just pay them without thinking about it. They must think we are really stupid. I called them up, and "eventually" I got a real person, and after a very long and unpleasant discussion, I found out that they are not associated with Cruising World, or anyone. Also, I have not been able to make them remove my name from their database either. I have been getting mail from them for years. So, I bet this collection notice you received may be something very similar. I would suggest that you call Cruising World's Customer Service and ask them. Don't penalize Cruising World just because some scum bag is trying to steal your money. Good luck, and happy sailing.
