Bought a ticket with what turned out to be a nearly impossible connection to make, spent 6 hours waiting for next flight. Went to cancel my return flight to avoid this issue but... cannot cancel, cannot get reimbursed. Hours on the phone being charged and no answer, with an answering maching that tells you to use a chat. I used the chat and after a very long, drawn out conversation, the person told me they couldn't do anything. Expensive lesson for me, but lesson nonetheless.
