minesthechevy, do not feel bad these "sale persons" definitely also play that fine game with the French. For exemple, it's a well know fact that certain telephone company use(d) to send rep(s) to someone's place to "inform" him/her of a product or to "assess" his/her services.
At one time or another there will be "just a little" document to sign (or even not) and, guess what, this or that old lady or trusting housewife will learn a few days later (most often before the end of the legal "délai de rétractation" ) that she has been "transferred" to Company X and "dégroupé" (i.e. opted out of France Télécom) without her consent...
Why should they bother? Statistically it's greatly profitable if you compare the small number of persons that will be "enduring" enough to get compensation from a Court and the huge number that will not bother or let it down...
