I booked two tickets in Qunar.com and paid successfully. After a while, I also saw that the order was issued successfully, but I didn't receive any short messages about the tickets.

As far as I know, Qunar.com is a comprehensive search engine, which collects the ticket information of all agents and airline ticket offices in the whole network, and also provides its own ticketing service. You can trade directly with Qunar.com through Qunar.com, or you can jump to other agent websites when trading. So you must find out whether your ticket is posted online.

As for your present situation, first of all, we must find out whether the ticket has been issued. Do you remember which plane ticket you booked? Check the official website customer service number of this airline online, provide your itinerary and personal information, and see if they can find it. If they can't find it, prove that there is no such ticket.

If there is really no ticket, you have also paid the money, and the rest is your road to safeguarding rights. Determine who the money has been paid to. If not, you can only call the police.
