Google India / Tez — money transferring fraud

I posted an add on olx to sell then some one called me and said i want to buy then he said ill pay you 28000 and then he said to install google pay so i can send you the money. I was not aware of google pay how to use it. Then he asked me for my upi id and qr code for money transfer so i send it to him on whatsapp then instead of sending money he requested me to transfer 30000 while he was on call and telling us to click on the pay button and you will get the money in account and he requested money in slabs of 5000 to 15000. I check with google pay where in there is no option or way to pay first and the receive the money.
I raise a complaint against upi id ([protected]@myicici) through which i received the request.
As per rbi regulation and the online money transfer app like phonepay, google pay etc are bound to get a mandatory kyc of each and every registers user. Hence i request you to arrange a refund from of 30000 which has been debited from my account.
If google pay can't help or arrange a refund then this will be further going to rbi as per rules and regulations.
