A councillor in Celbridge is urging people to join in a "complain campaign" about their bus services.
Labour's Ciara Galvin wants commuters from the Co Kildare town to lodge a complaint every time they're stuck on a bus or get left on the side of the road.
Dublin Bus's 67X express route to the town is already the tenth most complained about according to the latest figures.
The 133 from Wicklow, the 101 express service from Cavan and the 115 from Mullingar were other routes among the most complained about, according to figures from the National Transport Authority.
Outside of the capital, the 72 service which connects Tralee and Limerick to Athlone also received a high volume of complaints.
