Bharat Sanchar Nigam [BSNL] — repeated faults in bsnl landline

Address:

Khordha, Odisha, 751019

Since installation of land line with internet of bsnl in the year 2016 i noticed frequent faults. Despite i have been depositing the monthly dues. I have contacted local sdo, filed several complaints but to no effect. For few days i am getting line. But in other days the line becomes dead. Sdo is suggesting to change the bsnl line to jio. To my utter surprise thge sdo, bsnl telephone is getting his salary from bsnl and working for jio. What to do?? Please bring it to the notice of higher authority to resolve my problem.
