India Post — worst delivery service by the postman of tinpakuria post office branch

Address:

Murshidabad, West Bengal, 742202

Sir/mam
The postman, biswajit das, of tinpakuria b o of india post never does his duty properly. He never delivers important letters /parcels on time. Sometimes he does not even deliver it. There are many sufferers in this area who did not get their life insurance lic papers. People of this area many times complained the post master but no action was taken. Once he delivered my admit card on the day of examination. Now, my sbi atm, consignment no. Eb[protected]in is with him. Even after repeated enquiry he denies of such thing.
I request the consumer forum to take necessary step on this matter.
