I got an email ten hours before departure telling me the first leg of my flight had been 'retimed,' in such a way that I would miss my connection! There was no effort to fix the situation except for a link for requesting a 'free exchange,' which did not work. The email address was unresponsive and the chat line was useless, with no way to talk to an agent. I had to go to the airport in the hope that I could reschedule. Fortunately I could. Unacceptable level of service.
