Secure your WA immediately

I was layed off just recently, started to submit my resume and personal contact to local companies looking for a job, now I am getting phone calls and WhatsApp messages from fishy profiles, many attempts to hack my emai, FB and WhatsApp account. They sent me messages and call me trying to get my attention. I had to double my security setting up all sort of verification codes! They're desperate to get into my savings, they already got my full name, phone, email ...from my job applications.
