India Post — nsc amount not credited

Address:

500001

I had submitted nsc documents at parishram bhavan post office basheerbagh on sept 8 2018 as they were matured but till date amount is not credited in my post savings account. Department person balaji is not responding to my query on why it is delayed and not giving me any explanation. I request higher authorities to take necessary action. I have visited the post office more than 5 times seeking clarity on delay but no response from post office team. I also want to know why amount of 23.6 is debited twice for checking my post office savings account balance.
