Misleading time table

It upsets me that I googled the time table today for a bus from Kilkenny to bonteheuwel and the time table shows that the bus departs at 16:05 and 16:45 but I waited till 17:45 for the bus and it was no show and yet the time table was updated on the 05/01/2016, I finished at 4pm and only arrived at home at 18:20 due to having to take another bus and a taxi just to get home, this is completely unacceptable and its unsafe to stand on a main road waiting for a bus when the time table shows otherwise, I would sincerely appropriate it if you could update your times as soon as it changes so that I can make other arrangements to get home from work
