Bharat Sanchar Nigam [BSNL] — not refunding the security amount after one year

Address:

Allahabad, Uttar Pradesh

My land line no was [protected]. It was established at SIRSA HARYANA. I DISCONNECTED THE phone in may 2017. After that i am reminded again and again but nothing replied by the department.
As per rule security should be refund maximum 90 days. But I have passed above ONE YEAR (16 Months.
It is seemed that officers are not taking pain seriously to refund security to the customer.
I see many customers are rounding to BSNL office. But no satisfactory response given by any officer. They clearly says thay that can't do anything to refund your security. It will be released by AMBALA DIVISION.
I am 62 years old senior citizen, but nothing hearing. I also already lodge complaints online. At that time a call received by me at that said to me that your refund will be sent in JANUARY 2018.
BUT no result. I request you to kindly take action against defaulters officers.
