Never trust

I recently helped one of my known who I never talked much but he reach me out and ask some money with for help , I helped with amount of XYZ rupees through UPI payment then that known guy scammed me when he asked for qr code to return money . I simply given instead of giving upi id of number coz never thought this would can happens also .That known sended cyber crime money one day without my consent .I never asked also to return money .Then bank officer was my know person helped me to prove that I am innocent guy then I realised he was into illegal work and earn from this works only . Never trust anyone known , unknown everyis same . He suddenly blocked all his social contact , personal contact from me and went somewhere where we cannot find easily
