Looks like they manipulated their rates to be able to appear to offer larger discounts.
Main point of story:
Between October last year and March Amaysim Energy (trading as Click Energy) told consumers in Victoria and Queensland they could get discounts of between 7 and 29 per cent off Click Energy’s energy charges if they paid their bills on time.
The ACCC claims these representations were false or misleading as the discounts offered applied to Click Energy’s market offer rates, which varied and were higher than Click Energy’s standing offer rates.

Finally. These shocks need to be taken to the cleaners. Click Energy was so damn misleading.
