Someone called pretending to be our property and complained about my upstairs. Not authentic. What should I do?

If you have a good relationship with your neighbors upstairs and want to continue to maintain it, you can find a property, chat with your neighbors upstairs and explain the problem face to face.

The main content of the explanation is that the content of the complaint at that time has nothing to do with you, so it is not something that your family should complain about at all.

Require the property to install caller ID telephone, and record the telephone number and complainant's name in future complaints to avoid such incidents from happening again.
