India Post — postman not handing over the letter to my family

Address: 211010

Speed post tracking no — ed[protected]in
I sent a speed post to iti colony naini allahabad from new delhi, on 04.12.2017.
But the post man is refusing to hand over the envelop to my family member in iti colony naini allahabad and asking to see only "the person stated on the envelop and not any other family member".
Kindly tell ur post man that people go to their offices for work and cannot remain at home to receive the letter.
It can be delivered to family members also.
Is this the way post office going to ruin its name by harassing its own customers.
Kindly tell ur staff that this is the reason why people are switching to courier services.
Kindly look into the matter and do the needfull.
