False advertising

Every morning on Die Groot Ontbyt on channel 144, they claim that their POS (Power Optimisation System) can save a household between 30% and 50% of their electricity bill. This is hogwash and technically impossible. Gert can not explain how they achieve this and promised that their technical expert will contact me to explain. This never happened. Can only assume they are qualified in Snake Oil Selling 101 and are out to catch non technical consumers with unsubstantiated and outrageous claims.
