We did not, although I do accept we probably should have.
I made the presumption that since said traffic was transiting Banjul he or she would at least contact them.
We were about 20 nms from AMTAL try to get descent from Dakar when we noticed the traffic on TCAS. (we were also 2 way with Banjul tower)
We then had to set up an anticipated hold at AMTAL and try and contact this A/C. Looking after our jet and pax was the priority and we did try Dakar, Banjul and 121.5. Should have tried 126.9 I suppose but that is normally used by high level traffic for information as you know. Somehow I doubt this traffic would have been monitoringb126.9
We were very concerned about its varying altitude and then became more concerned when it started to climb directly beneath us at AMTAL. (It stopped at FL 95)
We asked Banjul to file a report and have filed both an ASR and MOR ourselves.
Don't suppose we will hear a thing as that is the way in these parts.
Kind regards
