spark fiber service

I am waiting for my fiber connection in Woodridge area, Already given the account no and phone and other details, but no date has been given for the installation, waiting for weeks now, I wrote to spark, did not get reply yet. I heard that local fiber co need to give the connection, chorus used to be the local Fiber co, but I heard that this area was given to visionstream,

I have no idea whom to contact now, any idea how to contact visionstrem?

thanks
