My phone is either dead and noisy every time i am complaining from four months every day but not bother mtnl employees and i have also send mail but nothing has done so far. Only sent bill every month. My wires box are broken from outside my house and these are 26 years old but they never changed. When i complaint about this next day they delete saying complaint rectify. Why i will pay monthly 300 rs. Either solve my problem and calculate accordingly when phone is dead and noisy. Phone no.[protected]
