INCORRECT BILLING, *****ING OF ELECTRICITY

I have had the unfortunate circumstance of having to deal with such an *********** company for the last 3-4 months. I am recharging my account almost every 2 weeks, which totals an amount of almost R 3000 a month. I do not entertain, neither am I at home during the day. so just where is all of my electricity going too?? I had also recharged just 2 weeks ago and had my electricity go off for 2 whole days. of which I was told their online system was down and that nothing can be done. Further to this there was no senior person I could speak to. I was told to send an email and it will be assigned to someone. Why do we have to endure costs for others who are clearly making a mockery of this prepaid system. How can Eskom allow such people into the market to rob the people in this manner?
