Mafco FC has written Football Association of Malawi (FAM) to lodge a complaint against poor officiation in second leg of the Airtel Top-8 match against Nyasa Big Bullets on Sunday at Chitowe Stadium in Dwangwa.
The soldiers were booted out of the competition through a 5-2 aggregate, after a 2-1 result on Sunday.
After the match, the team's coach Yohane Fulaye told reporters that the referee Mercy Mziya's was biased in her decisions.
Three days later, the team has taken a formal approach, as the general secretary, Anold Nkhoma has highlighted four decisions that they think Mziya erred in.
In the letter, Nkhoma claims Mziya failed to control the game, and should have awarded them a penalty after Peter Kasonga was brought down in the box in the course of the match.
He further alleges that Nyasa Big Bullets' goal was from an offside position, and that the assistant referee's flag was up at the time, but it was brought down to let the goal stand.
The team also thinks the penalty that was awarded to Bullet's in the dying minutes was not genuine because Bullets' Chiukepo Msowoya dived.
FAM is yet to acknowledge receipt of the letter.
Bullets progressed to the last four stage to meet Mighty Wanderers.
