The ticket was booked on the wrong date and changed, and it was unsuccessful after waiting for a day. During the period, I received a text message saying that my application for change of visa was rejected on the grounds that the rescheduling fee had been received. Do you contact the airline directly or change the ticket through the ticket agent? The speed of this change depends on the airline. Some airlines may change it slowly, but once they receive the money, they are guaranteed to change it. However, there are several domestic airlines that are rubbish, and you may have just met them. If it is an airline or a big ticket agent, it takes a day to tell you that you can't change your ticket, you can try to complain; If it is changed by a small agent, you can only admit it yourself.
