Life Insurance Corporation of India [LIC] — Credit of my LIC Premium to LIC account

I have a standing instruction for payment of LIC policy premium from my Bank of India account. As per Bank Passbook dated[protected], Rs. 18309/= was credited from my account but not credited to LIC. The transaction details are as below.
TRTR/LIC/298030/V/D[protected].

As this amount was not deducted from my account, I mad online payment for the premium for the same policy on[protected] from my another bank account, to avoid penalty due to late payment. This payment is reflected in LIC records and I received a receipt from LIC against this payment.

I contacted LIC asking for refund as there were duplicate payment for the same premium. However, LIC records shows only one payment received in their account.

How do I get refund for the amount from Billdesk?

Please check your records and credit amount back to my Bank of India account.
