Various election-related problems were monitored  by Kontra Daya volunteers based in the Western Mindanao Region.

Inefficient process. In Barangay Zone 3, Isabela, Basilan, long queues ensued from weak facilitation in the clustered precincts. Since 8:00 in the morning, only 4 voters were allowed to vote at clustered precinct numbers 065A, 64A and 61A. The voting process was reportedly held behind closed doors.
PCOS malfunction. In Malagutay Elementary School, Zamboanga City, Board of Election Inspectors were compelled to personally feed the ballots into the PCOS units due to the machines’ constant malfunctioning.

At Southcom Elementary School, Barangay Calarian, Zamboanga City, precinct 76-A voters were made to wait for almost three hours since the queues started because of malfunctioning PCOS machines. Elderly people also complained about the delay.
Meanwhile, at 11:00 am, a police officer admitted on radio interview that some PCOS machines and cards have yet to arrive from Manila.
Disenfranchisement. Kontra Daya observed that known members of a certain partylist were barred from voting in all barangays in Pitogo town, Zamboanga del Sur by the Nacionalista Party Coalition, which was reportedly in control of the Board of Election Inspectors.
Harassment. Kontra Daya volunteers themselves experienced harassment on the field. A policeman threatened to kick a KD volunteer at the Southcom Elementary School, Barangay Calarian, Zamboanga City when the latter attempted to distribute KD monitoring leaflets. When the volunteer tried to enjoin the policemen to report election-related problems thru Kontra Daya, the police element replied, “Di mo naiintindihan. Kanina pa kami dito. Baka gusto mo tadyakan kita. (You don’t understand. We’ve been here for some time. You might want me to give you a kick.)
