NBN Plan upgrade usually takes 1 day to complete but typically it can be less than 2 hours. Let us should you require assistance in regards with your NBN plan upgrade so we can chase this with our accounts specialists team.
NBN 12 was installed on 9 april,2020. I have already requested before 9 April to upgrade and install NBN 50. Now NBN 12 was installed on Thursday 9 April 2020, I have been advised that upgrade will take place somewhere on next Thursday 16 April 2020. Even though intially I was advised that upgrade could take only few hours...and here it is 7 day.
