Bad guest

[Hoang-Long0]

Good evening, I want to warn the bad customers who wish to stay free at home. They are Chinese, check in at 2:20 am and do not stop to call me and talk to me in Chinese, without waiting for me to answer them in English on the airbnb message. They said that my house did not have electricity with bad smell. I'm afraid they play deliberately badly to get the money back. .If I check and there are no problems as they say, do I have to pay back the money? Please answer my question soon, please. cordially
