I received a call from 9446 8532, claiming to be my ex-colleague who had changed to a new number. i naively revealed my company and asked him if he is from there and asked what is his job there. He answered yes and asked me to guess his name. I said I really cannot recognize the voice and refused to guess. He keep insisting that he had dinner with me before and asked me to guess his name. After a while of not getting any guess from me, he said nvm, I could look at the whatsapp pix later and hang up the call
