Hello. I am moving overseas next year and don't need my NBN anymore after. I am not on a contract and it renews every month on the 30th. The last date for me wanting NBN is the 30th of March. What exact date do I have to give notice about cancelling it and it will not cost me any more money? If NBN cancelled on the 30th of March will that be the last bill. I have read other peoples on here and am confused on how it works and would like to now for my situation.
