Tunisia's football federation (FTF) has written to the Confederation of African Football (Caf) to complain about their game with Mali ending 13 seconds early.
The Tunisians were trailing 1-0 when Zambian referee Janny Sikazwe, said to have suffered sunstroke, blew early.
He had already whistled for full-time after 85 minutes, only to notice his error and continue the match.
"We will do whatever it takes to defend the rights of the national team," FTF official Hussein Jenaieh said later.
"We are not children."
