There can be many times when a taxi driver will not pick you up.
They may also refuse to use the meter and overcharge.
Whatever the reason, if you feel the need to report a taxi driver:
You can report to the Land Transportation Department using the hotline number: 1584. You’ll need to take a picture of the car plate (inside and outside the cab). Alternately, you can download the DLT Taxi app to report the taxi.
