I have paid the premium amount of Rs.1875/-(one thousand seven hundred and seventy five) to National Insurance company on 24.01.2018 (Ref. No.[protected]IGACTYFCP6). The above said amount has been debited from my account and got an error message which states the debited amount will be reflected in my account on next day, but till now the amount is not refunded. So I hereby request you to kindly refund my money at the earliest.
