Another R1300 ERROR AGAIN

1) Our electricity bill has been incorrect since April/May 2015. The estimated amount has been added onto the actual amounts, over and over again. My husband has queried this numerous times and received numerous reference numbers but still this month, Eskom cut us off and we had to pay almost R3000 to get connected again. Never mind the fact that we did not owe that money in the first place.<br> <br> 2) We have since received ANOTHER statement with an error on it amounting to R1300. Eskom have done it again right after the last mess up.<br> <br> Really? Is this what we have to deal with? Eskom still owes us R2500 never mind the refund from the above R3000. Who do we deal with here when no one ever calls you back?
