What's the matter with Ctrip always queuing up for manual customer service?

Ctrip always queues up when transferring human customer service, because it is often necessary to listen to the prompt tone before entering the operation instructions of human customer service. But if you miss the content or don't press the button for a long time in this process, you must listen to the instructions from the beginning, and the process of switching to online customer service often lasts for a long time. Sometimes it is not an exaggeration to display hundreds or even thousands of numbers. However, it depends on luck whether you can successfully switch to manual online customer service. If you don't do a good job of diversion, you may be in a state of waiting in line all the time. If you miss it, you have to queue up again, or wait until the end without waiting for manual customer service, but let customers find time to redial.
