Lucky to see Adele in Chicago on Sunday night! Call the center in advance because we have unsold tickets, and then we have a problem paying by credit card. Customer relations staff told us to arrive at 6 p.m., when the door opened, and then go to the booking office. We planned to arrive at 6 p.m. and we arrived. The man is rude at the booking office. I know he has many problems to solve, but why is he so rude? We kept queuing, and then it was almost 6:45 without opening the door, and the concert was about to start at 8:10.
