@witguru As far as I know the billing will be as usual. My experience is that they adjust the caution deposit advance in later bills. For that, at time you need to call BSNL and ask to acccount officer to facilitate the deduction. But recently someone stated here that you advance will be refunded only when you surrender the BSNL connection. I am not sure if it is still there and valid in your circle.
