Same problem, over billing, again, and again

Gross incompetence seems to be the order of the day at Eskom. I again get billed an extraordinary amount, that has no relation to my use, as captured online. Last month my bill was R4153 and now this month it is R1480. How is this possible? This can only be true if I was over billed! I think I will have to take this up with the consumer protection, ombudsman / small claims court and get my interest back, as well as damages as per previous compliant. This is becoming ludicrous..
