12306 After the train ticket booked online was refunded on 12306 website, no SMS or email prompts were received. The ticket shows "Refunded". Did the refund succeed?

I also refunded my ticket last night. The results showed that the system was busy, I didn't receive any emails or text messages, and the money didn't arrive, but the order showed that my ticket had been refunded. I don't know what to do. Call the bank, and the bank says it wants to find a merchant (that is, the Ministry of Railways). The bank is responsible for supervision, and the merchant has to refund the money first. I called 12306, and the customer service staff said to return it to me within 15 working days, excluding legal holidays and weekends. I said/kloc-what should I do if I haven't paid it back in 0/5 days? My kind sister suggested that I brush the passenger's ID card at a nearby sales point after work. If a ticket can be issued to show that the refund is successful, I will wait patiently for the refund. What's the problem? Then call the railway or the bank. Oh, it's really complicated! I hope I can get a refund soon! ! !
