India Post — Regarding Death Claim for Nominee

Hi Sir,
Death Claim has been submitted to India Post at Vile Parle . The address is
Ground Floor, Srinivas Building, Paranjape A Scheme, Road Number 2, Near Sun City Cinema, Vile Parle East, Mumbai, Maharashtra 400057
The claim has been submitted on 7th May 2022 and verification person visited on 1st June 2022 at home when I was told a letter will be sent 15days from date of submission and within 1month the claim will get settled by pay order in the name of the nominee. Still this has not happened. They have delayed it for more than 1 month and still no progress seen from them.
Can you please help speed up the process
