What should I do if I am pestered by my ex-boyfriend and call and text every day?

You can install Tencent mobile phone housekeeper, turn on the "harassment interception" function, and then set the interception mode to "only accept white list" or customize the interception mode to "intercept strangers' calls", so as to intercept VoIP accurately, and the telephone contact in work and life will not be affected by harassing calls!
