Not much consolation to you, but ground transfers at CDG (and ORY) are one of the shortest ways to bring out the thorough incompetence and self-centred nature of Air France and those it chooses to sub-contract.

A blend of handicapped and Premiere expectations led the Napoleonic airline to screw me up a few years ago.
Nowadays, their handicapped sub-contractors are best left beyond description. Let it be said that I, my company, all those whom we sub-contract are instructed to avoid AF connections at CDG like the plague. Yes, avoid it like the plague. They are the equivalent of brutal thugs.
