The General Manager,
Mahanagar Telephone Nigam,
I would like to bring to your kind notice the unsatisfactory working of my telephone no. 3276174.
It has not been working properly for the last one month. Sometimes the bell starts ringing, but by the time we lift the receiver, the phone is dead. Thus the incoming calls are received, but the outgoing calls are not possible. Now it is completely dead.
We have lodged several complaints but to no avail. Therefore, I request you to look into the matter and do the needful.
