State Bank Of India [SBI] — unauthorised upi transaction regarding

I am defrauded by a fake customer care executive named amit Mishra as displayed on true caller. that number was [protected] of go2shop e commerce site. actually I ordered a mobile on that site on 1st may 2020 after 12 days I have not received any message regarding my order so I searched customer care number on google. I called on above mentioned number he told me we can place your order due to lock down so company decided to refund your money and he insisted me to forward a message to his number by sending a link to my registered phone number. when I did that I got a request on phone pe to send money amounted 9999. I asked him why should I transfer to you this amount as I ordered a phone of rs. 2999 and you are viable to refund it to me rather. in the meanwhile somehow he hacked my account and my account has been deducted with 9999 rs. two times and 5000 rs. once. I have utr. transaction no. of phone pe transactions. but for 5000 rs. I only received message of deduction from bank. then I called on sbi customer care no, but due to lock down customer care executives are available only 8.00 a.m. to 8.00 p.m. so I called customer care for unauthorised transaction and executive told me to lodge FIR at cyber cell as they could just disable upi and devit card.
