Scam or not?

In March I fell into a trap set for heffalumps by an outfit producing a CD with the title World Business Guide.  I mistakenly signed for an insertion, thinking this was free #, like various writers' directories I've had entries in over the years.  The word FREE was in bold and I omitted to read the small print (oh, what stupid trust!) .   I did not understand that by signing I would be billed for 995 euros each year for three years unless I cancelled within two weeks.  Apparently this outfit has appeared in various guises, based in different countries, Nevis in the West Indies and the Netherlands among them.  I'm by no means along in becoming a victim.  I'd like to hear from anyone else who has fallen into their trap.
