Beware Of Whatsapp Scammers

This no 0814 693 2838,called me that he's from a group that I was also in,and he said there's a program we want to hold online,that I should call him a code that will be sent to me so as to add me to the program,I was busy on site so I just called him the no,so I can continue with what I'm doing,but immediately I called him the no,it just dawned on me that this might be a scammer,immediately I tried accessing my WhatsApp but I had been logged out but for the two step verification pin I did,It would have been hacked by this unfortunate fellow.
