Why can’t I get through the phone number 12306?

I just called 12306 but couldn’t get through. After waiting for a long time, it kept saying busy, so I checked online and found that there were many people like me. I thought it was because there were too many people when I was playing, so I wanted to play at another time. But now it seems that I don’t want to play again.

I booked a ticket online yesterday and the payment for the train ticket was successful. Ordinary express payment failed, I didn't write down the error code or anything. I didn't have time to check online banking.

Then there is online ticket booking. I don’t know who manages the website. It is even more rubbish than the bank’s website. Garbled characters appear many times. I don’t know what they spend their money on and what server they use. They often get stuck and can’t access the server. Could it be that they use a free online server?
