Life Insurance Corporation of India [LIC] — Survival benefit paid in part - balance amount not paid so far

Survival Benefit of Rs.37272 out of Rs.40000 payable was credited to may bank account on 21.03.2021 under policy no.[protected] by LIC . The balance amount of Rs.2728 to be paid to me has not been paid by LIC so far even after making several requests over telephone and sending an email by your customer service personnel pointing out the issue . So I humbly request you to redress my grievance at the earliest since two months time has already been elapsed after the first part payment.
Thanking you
