AF was also in my case really fast to refund such expenses - about three working days until confirmation. Make sure you explain your claim without all the emotions above, factual, and as short as possible.

Asking your doorman to reject was most probably not the best idea - you effectively asked a third party delivery agent (who wants to get rid of the bags as fast as possible) to return your luggage to their delivery warehouse which is potentially not even located at the airport to return it to AF where they most likely never dealt with rejected luggage and need to find out what the process for that is. For the future (not helpful now) best to ask the forum immediately if there is trouble brewing.

On a positive note, you will be reunited with your luggage eventually. Hope you will still enjoy Paris.
