Deutsche Bank India — denying to reverse the amount debited from my account

Beware of this cheating foreign bank in india which exist and they don't even follow any banking rules at all set by rbi. They only to know how to give mental torture to customer due to their lack of knowledge in banking.
It's been a week bank has failed reverse the amount and to provide even any details about this transaction for wrong debit happened from my account. On 19th jan 2020, i was in a call when i see a debit alert sms from the bank received at 4:15pm and i have immediately reported to stop the payment. This was a fraudulent transaction in the name of consumer complaints, fraudster used my newly created upi id and the amount has been debited. The bank did not register the complaint to reverse the amount. Later after i wrote an email with wrong upi id of mine then they registered a complaint. I did not intended to send money to "[protected]@okaxis" at all but bank is forcing me saying that i only transferred to close the case. Bank customer care has no rights use abusing languages to harass me. Someone called from a spam number at night 8:30 pm on 20th jan 2020 and asked details from my end which i have provided. He was trying to close my case saying if i have entered a wrong upi id it was my mistake but when i informed him as per rbi guideline they failed to execute stop the payment request made by myself immediately after seeing the message. They don't have adequate facility implemented in their banking system to stop the payment it's not my fault. Even rbi has told due to inadequate facility to stop payment request payment, bank is the culprit. He told he will get back to me and hanged up the call. On 22nd jan 2020 again a new person called me asking the details from beginning. After explaining him 6-7 time then also he was shouting on me that i did not tell him. Please stop harassing me this way. I have requested him to listen to the same call to realize how many time i have told him. No doubt he was bullying to close the case. Till that time bank has not even tried to give any details about which beneficiary account the amount has been credited and all that they admitted is it's fraudster account the amount is credited and i am innocent. Before calling me he was not even aware of any of the details of my case and he was trying to forcefully close my case. It's a week now bank is trying to close my case without reversing the amount.
Bank has also lied on 23rd when i called up they have asked to download their mobile app and rs250 voucher will be given but i did not get any voucher till now, this itself proves how this bank is working. They only take time and call me threatens me and their fraudulent transaction team totally full of goons to bully customers to close the case.
Kindly help me to get my money back as soon as possible.
