AF/DL/KL share customer service based on region. If you call from the US, you'll get DL regardless. In theory, all have access to each others systems, but YMMV. If you want a specific airline's customer service, twitter is your best bet. Historically, klm.com is best at dealing with multi-carrier itineraries, though things have improved a bit lately.

Did you book at airfrance.com or delta.com?

Also, if your concern is just getting credit for the flights (since you said you have no status), I wouldn't worry about that too much. DL is pretty good about fixing posting errors should they happen.
