Welcome to the community!
Thanks for raising this to us, we'd love to help and see the status of the NBN speed boost for the service, to better understand please shoot me a private message with your account details (Username/Customer ID together with the address on file).
I received the A free internet speed boost is coming your way! email back in Feb but I have no received any boost to our internet speeds like advertised. I have tested my connection using Speedtest periodically and have noticed no increase in download speeds
