Why did you get a message saying you were going to take the train after you refunded your ticket?

Your train ticket must have been refunded at the train station. The railway station and the online shopping website are not a system. If you refund your ticket at the train station, you need to contact the staff of the website to give you a refund. If you don't contact them, it will take about 15 to 20 working days to get a refund. You must have complained about the payment because you thought you wanted to ride normally. That's why there was a short message.
