Kiff No Beat concert in Cameroon, another scam?

The e-flyer above was plastered all over Douala for the promotion of a concert which was supposed to feature the Ivorian rap group; Kiff No Beat, as the main act. The concert was scheduled to be at Parcours Vita, Douala, Cameroon on the 22nd of December 2015.

A press conference was held, announcing that it had been postponed to the 2nd of January, and then Kiff No Beat took to their twitter later on, to announce that the concert would not hold because they haven't received any payment in advance and the event organizers haven't been in recent communication with them. Sad news for the fans...and to think that these flyers were plastered all over Makepe(the said venue of the concert)....smh! What really went wrong?
