India Post — Not providing a post office money receipt after receiving money and misbehaving with customer

Address: East Singhbhum, Jharkhand, 831012

I have visited to buy NSC certificate of Rs. 10000.
The officer (speaking orria and bengali) sitting in front desk was not giving proper instructions how to buy a certificate and after giving the money, he denied to give a money recept of 10000 Rs. And badly misbehaved with me .Given a normal hand written paper with written statement that received Rs. 10000
The officer is rude illiterate and having a bad attitude . He doesn't deserve a place in front desk.
