UNABLE TO PICK TICKETS AT THE STATION

Hello, I recently ordered ticket through 12306.cn and when I went to the ticket office at Beijing Railway Station (Central) they would not print my tickets as the woman behind the counter stated that our names were in the incorrect order to our passports (my friend and I are UK citizens.)

The names were spelt correctly and the information was in the correct boxes when filled out on the website, however they refused to print the tickets and made us buy tickets for 400 yuan extra (we had to refund the existing tickets- losing 20% off the original value as we were travelling that evening.) They would not re-sell us our existing tickets saying the train was sold out. This was at the English speaking window.

I just would like some reassurance that if I was to book through your website, that this would not happen again, as I presume the eticket number you issue after purchase is via 12306.cn.
