UPI — amount deducted.. transaction successful but not credited to beneficiary

Hi,
I had done upi transaction on paytm. I was transferring money from my one bank account to another. The transaction was successful initiated on paytm and amount got debited from my account. The receiver didn't received the amount as the transaction got stuck at npci. After waiting for 2 days and contacting paytm again and again they said that the amount was credited in the beneficiary account. The amount has not been credited in the beneficiary account and i am stuck with calling each and every customer care to help me but all i hear is the hold tune from everyone. I request to kindly help me in getting my money back or getting the money credited in the beneficiary account.
