India Post — wrong pin code mentioned in the registered post by the sender.

Sir,
An important registered post had been booked with consignment no. - rc[protected]in from durg (C. G.) on 14 march 2020, with wrong pin code. While the actual pin code was 486889 (Singrauli colliery, m. P.) it has been mistakenly written as 485001 (Satna m. P.) by the sender.

The consignment has been moving between satna (M. P.) and waidhan, dist. Singrauli (M. P.) for the past 25 days but has neither been returned to the source address nor has been delivered. I have tried to call post offices in satna but no response has been received.

Sir, it is a very important service document please help. I am providing the details below:
