Saraswat Bank — Someone is using my mobile number

There was a payment done by my friend, and the money was supposed to come in my account which is in punjab national bank, he used phonepe platform and sent it using mobile [protected]@ybi and the account got transferred in another account which was in rhis bank.
so it seems that someone else has an account linked to my current and authorized mobile number. Please look up into the matter asap.
