1.4 Impact of Customer Satisfaction on NBN.

On a five point scale, how happy are you with the NBN?
Very Unhappy | Unhappy | Neutral | Happy | Very Happy.
Relates to delay to install, service, reliability, help fixing problems, price etc.
Impact:

Lower satisfaction increases switching to mobile only, less revenue, minimising use.
Higher satisfaction increases revenue, increases power usage, decreases switching to mobile only.
