I notice whenever I chit chat with customers thru WhatsApp that i can’t provide some services due to company shortage of manpower.. to my surprise is that after few days I will received lot of WhatApp/ email / call from foreign agencies wanted to offer me foreign workers… agencies are from China India Bangladesh and Malaysia and local anyone here accounted same issues?!!

I won't be surprised. Until now I wonder how WA makes money.
This is why I am using separate old Samsung phone running Android 4.1 to install Whatsapp...alot of functions will not work.
Aiya all these free software are free for a reason.
Whenever you use them, you're updating their database automatically. Otherwise it's very costly for them to do the updating and remove those outdated
My advice never use WhatsApp to chit chat with you 小三
