ICICI Bank — Deduction of money for a policy, I have never enrolled for.

One day ago (28.09.23) when i checked my account balance, I was shocked that around 1900 rupees where missing i checked all my transaction history of all upi apps but there couldn't find anything but when i checked my bank statement there I got to knew that 1899/- rupees where deducted for some "PPL/WPP_SR**********_Renewal of Policy" on 26th of September, 2023 which I have never enrolled for . There was not even a single message about the dedution of the money. I kindly Request for the money back!, its huge amount for a student.
