Put him in a coma. You can hack him through Tencent mobile phone housekeeper.

On the housekeeper's safety protection page, select the one intercepted by harassment, and select the setting in the upper right corner to add it to the blacklist.

If there are harassing calls in the middle of the night, you can turn on the housekeeper's night anti-harassment mode.

You can choose the white list of allowed start and end times or the ringtone in the communication.
