Arrived to the coach in Belfast to head to Dublin. Was refused entry to the bus as the driver had sold our tickets to someone else??? (Would love to know if that was official or cash in hand) He was beyond rude and actually quite intimidating. When I asked for a refund he refused. Once I asked for his name so I could lodge a formal complaint he turned his ID card around so I couldn't see his details and refused to give me his name. We then had to walk to the other side of the city to get a train to Dublin instead. On the way home from Dublin to Belfast, 15 mins into the journey we were told to get off the coach and onto a different white coach from another company (so why did we pay Aircoach) which was half full so we were packed on. Shocking, won't be using Aircoach again
