National Payments Corporation of India [NPCI] — google pay upi fraud

Some person call my father today 30dec 2020 in evening from phone number-[protected] as a known pandit ji with the same voice, that he need money urgently, so can he transfer some amount of money into my fathers account as he dont have google pay or something .my father add me into a call with him. After some time a person called me that u have talked to pandit ji . But i cant transfer money online directly as he has a merchant account so he send me a qr code voucher so that i can scan it and get money from him.i scanned it first for 2 rs as 2rs debited and 4rs got credited and i also confirm the new number with the conference call i get with my father as from a person named pandit ji. So i get confirmed, then. He sent me a 20000 rs voucher he said you also have to enter your upi pin with for the transaction to happen . But as i have said first i confirm it with pandit ji number, but then i dont get my 20000 +5000 extra back, as both pandit ji number and extra number are fraud. But voice of pandit ji is same as originally he has in my relation and he know me father and chacha ji number also.
