Phonepe APP - Fraudulent call

I recieved a call at **.** am *th Jan **** saying he was from PhonePe Customer care and tole me that i have recieved cashback of **** Rs. and in order to avail it i have to open my PhonePe app .
When i opened the app i got notification of **** Rs. but there was only Pay and Decline option so i questioned him that the money won't be credited to my account instead it will be debited from my account still he somehow convince me to proceed by entering password and then told me that i will get the money once this process is done. But by doing so my money got debited from SBI bank account so i questioned him that i did not get any money and i asked for refund. Then he did some processing and asked me for toal bank balance i have in my account.I had **** till then but i only said **** so he again sent request fro **** rs saying that i will get refund only when i do transaction of **** i.e. all the money left in my account.I questioned him argued with him saying that i won'y fal prey again and please do the refund of **** but he kept on insisiting that till **** has not ben sent i won't get the refund and also conviced me saying to record the call and complain if i feel there is any scam . So in order to get my money i again did payment of ****.Still i did not get any money..He again said that i haven't told him the entire amount and that's wy i am not getting refund and then the same cycle i had to do payment of *** which he sent request for. At the end he said i would get ***** Rs i.e. my bank balance plus rewards at * pm.But after that i never got my money nor is that guy recieving my calls.
