I was literally having a conversation with an agent who just randomly stopped replying to me out of nowhere when I was just trying to upgrade my ticket. That was literally the last good seat in that section, and they ruined my chance of getting it. Just terrible. Whoever came up with chatting via text and not telephone for customer service really dropped the ball. Just inconsiderate. This is my very first concert. What a distasteful experience to be welcomed to. Thank you for nothing, Ticketmaster.
