Is it safe to book a hotel on booking.com? What's the customer service phone number?

As the saying goes, cheap stuff means no good stuff, let me tell you about my situation. I booked two rooms online using "booking", but they missed it! ! The foreigner couldn't find the order number and got mad at me! ! Hold! Is this China good? ! ! Dragged to China! If it weren’t for the fact that we were late and didn’t have a hotel, we would just have sex with him! ! Sigh... Normally I don't say bad words, but you didn't see him like that. He was really bullying and infuriating! ! ! But it’s also my fault that I’m not good at English and I’m bullied, so I can only endure it…. Finally, let me talk about the customer service, which is even more irritating. The first one negotiated with me and said he would find a hotel for me, but then there was no news for an hour or so. The second one was even more awesome and made a few mouthfuls. It was over, and then they refused to answer my call. At first I didn’t believe they were so brave, so I called from another phone number, and the call went through. Then I said I wanted to complain, and then he said they had no customers. The service number only had a name called "Julia". I was very angry at first. Later, the person named Julia was very dedicated. She went to the supervisor and told us to find a house by ourselves. If we found it, we would pay first and then "booking" "They found us a price difference. Then we went looking for a house in the middle of the night. We looked at many hotels, but none of them were available. So we called Qunar. They said that all the more than 200 hotels they cooperated with were fully booked. Finally, we had no choice but to return. In the hotel, the boss later changed me to a double room, but because it was not good for me to be of the opposite sex, I still hesitated, but there was no way. Just when I was about to give in, God opened my eyes, and the guest who had booked the hotel to change rooms was not came, so we basically solved the problem in the end. In short, I will never book a room with "booking" in the future! Really they are simply lawless! If you want to complain, there is no one. You should go with Qunar or Ctrip. It’s more expensive if it’s really expensive. It’s better than sleeping on the street. In short, there are still many, many unhappy things. If I tell you half a lie and someone still doesn’t believe it, then you can contact me and I will show you the records of my “booking” phone calls to collect evidence. I kept it, because it was too much, so I thought if they didn't care anymore, then I would have no choice but to call the police! That's why I recorded those phone calls, but when I called around 2:00 to ask about the final situation, the customer service staff was really nice and kind. In short, after this experience, I think I will probably never choose "booking" again in my life. I've really had enough.
