[Resolved]  Bharat Sanchar Nigam [BSNL] — Not returning back the refundable security deposit

Have surrendered my BSNL broadband/Landline connection with Telephone#[protected] on September 2019 with closure letter including my bank details where the refund amount needs to be credited back.

Its been a year and more and till now i have not received my refund amount.

While submitting the request letter, BSNL has promised me that within 3 months(90 days) my refund amount would be credited to the submitted bank account.

Need assistance for such a poor behavior of BSNL in not returning back the refundable security deposit.
