I signed up to AGL on the basis of a fixed rate (all day - peak and non-peak) but as soon as my account was setup it was changed unilaterally by AGL to a Time of Use plan with vastly different rates. Notification of the change was provided prior to 6am in the morning on a Sunday which appears to be deliberate to avoid me noticing. I wouldn't have signed up if I knew this was going to happen.
