Bharat Sanchar Nigam [BSNL] — Landline down and not repaired

I have a bsnl landline connection[protected] that has regularly had issues but last month it stopped working completely. I registered complaint and the person who came said whole line is down and will have to be changed. I have raised multiple requests but each time the ticket is closed saying updated as per cr 2065. I have 4 complaints that are closed like this with noone contacting or helping. Please tell me if it cannot be fixed and I can finally just disconnect the service and stop wasting money on this pathetic service. I have mailed the nodal officer Shri K.V.N Rao but no reply as well. Let me know so I can get done with this as I cant run around anymore.
