Mahanagar Telephone Nigam [MTNL] — Telephone not working

Address:

New Delhi, Delhi, 110009

My landline telephone & Internet is not working for the last 10 days now and i have complained so many times. Yesterday I received an SMS that it is being attended and also, the contact no. of the person to contact if the problem is not solved. But still neither the phone is working nor the contact person is picking up the phone. My connection is very old that is why i was continuing
with it. Some time back, also, almost 4 months my phone was not working properly and after so many complaints, they did not solve it. MTNL is very good at sending the bills on time. Except that, their service is 3rd class.
