I was on the 706X Galway to Dublin service. On entering the outskirts of Dublin it was clear the driver was having problems with the bus and had to pull in a couple of times. I understand these things can happen however after making a phone call the driver then said to us that the bus would be unable to make it in to Dublin City and that he would need to go straight to the airport where a transfer would be arranged to take us from the airport to the city. This was at 9pm at night and would add another hour on to our journey so me along with some other passengers got off and had to arrange our own travel from the side of the road. No rationale was explained for how the bus could make it to the Airport but not the city. To top this off I received an email a couple of days later that my return trip was cancelled due to unforeseen circumstances. So really both legs of a return trip were incomplete.
