Massively incompetent. I spent three weeks trying to make a small change with a booking. Spoke to at least 10 different staff members by phone and email and including the floor supervisors. Everyone blames everyone else or gives conflicting advice. Can't cancel an unrelated domestic flight that was made as part of a multi-stop international booking because "the outbound following flight will also be cancelled" with no attempt to identify who the party is that's cancelling this. The airline was happy to cooperate if gotogate would contact them directly but gotogate didn't do this even after many times that they said that they would.
