BSNL — Issuing bills even after surrendering the connection

Address:

sankara giri kilimanoor 695601

I applied to the JTO Kilimanur to cancel my landline connection no [protected] on 16.1.20. I surrendered my telephone instrument and got it acked.Ever since the Accounts officer is raising bi monthly bills and recovering it from an adavcne of Rs 1500 I had with them at the time of application.Last such bill was of December 20. The JTO Kilimanur could not resolve the issue obviously be cause he has not taken prompt action to inform the matter to the accounts officer.My request is settle mtter and refund the irregularly recovered amount with the security deposit imemdiately.
