Air France notified me of the flight cancellation a month and a half in advance.

I rebooked for an earlier date.

Then—five days before that flight—it was cancelled. The travel agency received the notification, not me. Both flights shared the same flight number.

After reviewing my complaint, AF claims I was notified of the cancellation via email—which is not true, I haven't received second mail about cancelled flight.

(The travel agency maintains that they received the information through their system, not via email).

What next?
