Postal Life Insurance [Pli] — Postal Life Insurance [Pli] issue regarding premium payment

I have policy in postal life insurance, Bhavnagar

My policy number is:[protected]

I have paid premium of one months august 2020 12:30 pm
Amount was : 2403

There was an error while online transaction so i repeated the transaction again for two times.
After 10 minutes I got a message from the bank that the amount was debited two times from my bank account for the one premium (I. E: 2403+2403). So, amount of 2403/- is applicable for refund

Kindly look into this matter and do needful.

Here I attached the transaction history for your reference.
