Flying Clog
Europe is far from perfect. We were North of Nice headed to MXP when we got a traffic warning. A quick look showed a aircraft coaltitude at FL330. We attempted to talk to the controller without a reply. Acquired the traffic visually about the time we got the TCAS climb climb call out. We initiated a climb and tried to tell the controller we were climbing but a flurry of panicked French transmissions broke out on the frequency. A A320 passed right under us. We again attempted to talk to the controller with no reply but still lots of loud French. Returned to FL 330 on our own and no French controller would speak to us again. Had to effect our own frequency change to the Italians. Using multiple languages on the same frequency should be banned.
