Tshwane is systematically de*****ing customers

In December 2014 I complained to Tshwane that the so-called estimate of my electricity usage was unrealistically high, and that I would pay R3250 instead of the R5800 on my bill. This was accepted by the person in the call center, and according to him, a note was placed on the account. In January, after having paid the R3250 as agreed, I phoned again to find out whether there was a problem with my account, only to be told that it was up to date. At the end of February, however, I received an an account for R7800 which included a fee for final demand that was never delivered, a cut-off and reconnection fee, that was never done and on top of that an additional R2750 security deposit. Many e-mails and phone calls and visits to the offices in Centurion resulted in a letter stating that all their actions were in accordance with their financial guidelines. I still have not received any proof that the power was cut or restored.
