BSNL North Paravur Kerala — Non rectification of telephone line

Address:

Kollam, Kerala, 683520

I have registered a complaint three month back about non proper functioning of landline phone 2447972. Then its worked for two days and again started non functioning there after when I again registered complaint three weeks back from today. Some from bsnl visited but phone still not active. I called up the office and requested for rectification but no action so far. I request action against the officer who is responsible for this as its almost a year non proper function of phone
