Booked a ticket with Delta recently and paid an extra $130 to pick our seats. But guess what? The seats didn't show up when I checked later. Tried to reselect and they wanted another $40+ per leg. Contacted customer service, waited over an hour to get through. When someone finally answered, the rep was super rude. She kept cutting me off while I was explaining the problem. My wife was giving her dad's birth date for his ticket, and the agent rudely asked why she could hear two voices, then just hung up on us. This is not okay. Delta really needs to improve their customer service and train their staff better. The whole experience was so frustrating and disappointing.
