It is not above Rs 6000/-
Puja tried to clear the issue with Net amount
for broadband Rs 2150/- !
you paid Rs 500/- at the BSNL office .
I assume that you didnt opt for STD/ISD calls .
so no deposit for this .
Modem is on rental . so deposit for modem is to
be collected . Rs 500/-
one month rental advance is to be taken Rs 900/-
present month bill Rs 900/- + modem rent Rs 100/-
so it comes to Rs 2400/- for the first bill .
this is my understanding & I am sure that
if you donot use phone for regular voice calls
then your first bill is within Rs 2500/-
(service tax + Ed cess Extra)
