On Apr.18th a booking was erroneously made on a return ticket line 700 instead of 702, from Dublin Airport to City Center. The tickets were for the days of May 16th and 21st. I notified immediately about the error and asked for the rectification and procedure how to do it. The reply was totally negative!!! I believe that refusing the rectification after an immediate notification, with about 20 days for the correction, is simply ludicrous to say the least… Of course I will not go on the bus and my money are lost instead of changed to the other line departing from the same location…
