BSNL Landline — Landline telephone faults not rectified at PO-Garhi Cantt Dehradun Pin -248003 Uttarakhand Dehradun

I have lodged many Complaints regarding my Land line telephone faults. The phone remains faulty most of the time. Several complaints yielded no posisitive results. On an earlier occasion the SDO phones himself advised me to go for disconnection of the subject phone.
On my recent complaint I am provided with a contact Number of a technician. On contacting him he too shown inability to rectify the phone. He rather advised me to contact the SDO indirectly hinting me to go for disconnection.
Can this matter be resolved
