Here's an update: when this scam happened to me it was in 2017. After i followed the police advice (i.e. change number, close account) everything was quiet.
So imagine to my surprise when at 1400hrs today i received a whatsapp message with a video of a house gate burning with an O$P$ message next to it.
Luckily there is an npc nearby so i went to make a report.
Sigh ... when will this **** end? Even after two years, this thing is back to bother me. Have to stay strong and alert. My parents are old, if those shits do anything to my home, i'll do anything to protect my home and family
As for why still can contact u if can deactivate your fb account do not link your phone to any social media .
