MTNL Mumbai — bill charge even when no services for weeks in mira road

Mtnl in our area has been down for weeks now, and yet they send bills and say that its a municipality problem and not a mtnl problem and we have to pay the entire bill.

A lot of people in mira road have applied for disconnection or waiver off the charges, but to no avail.

Mtnl is forcing subscribers to pay without service
They outright say that they will not fix the problem as its municipality problem cos they have dug the streets for concretization of roads.

I think its unfair to charge subscribers anything if they do not provide services
Please help
