i dont know how they got my personal photos. But he sent me a whatsapp before i changed number. With pictures of me and my family. Saying he will send to everyone in the vicinity. Or should i remain contactable so that i can delay?
They can get your personal photos easily from social media once they have your name and your phone number. Since you have already run your AL and made a police report, don't contact them anymore. There is no "delay" tactics with them, only endure their harassment. The more you maintain contact with them, the more they will continue to harass. Why would you want to do that?
Just make sure you have these things done:
1) Police report
2) Inform NOK and company
3) Buy and install a CCTV
4) Change your phone number if you cannot tahan their calls and messages
