PhonePe — refund of fraud transaction

I was victim of fraud transaction of sbi atm card of rs. 9999/- dt. 22-may-2018 by fraud phonepe user. I have called phonepe customer care to cease fraud user wallet by sharing transaction sms details and phonepe had blocked user wallet and requested me to raise cybercrime complaint through cybercell of respective police station to get refund in my account. I did it and phonepe asked me to share all details regarding passbook/identity/consent letter. I shared all details with phonepe and they initiated refund with arn [protected] dt.[protected], but there was no refund amount in my sbi account till date. I contacted phonepe regarding no refund, they told me to raise chargeback request to bank. I did it, but sbi replied that there is credit amount in your account. I contacted phonepe regarding this, but they are not sharing any details of transaction like transaction account, date, amount etc except arn. Please help me to get my refund back. My phonepe complain id is 13974960.
