Power Service from City Power

We are experiencing a problem the electricity recharging device. It has been giving us an "error 30" since Thursday and we are unable to recharge. We are running out of electricity and called City Power at 9:00am this morning. We were told that they would assign a technician to come to our house, Ref no. CP***. We just called again at 13:40 to follow up on the call, and we are now being told that the call was logged as per reference number but no technician has been allocated to the call because there are no technicians available in the Roodepoort area. So what am I expected to do in the meantime? This is the same City Power who has increases tariffs ridiculously but we as customers are expected to accept poor service. The agent didn't even give us a solution. We must just sit here, hope an pray that someone comes to attend the call whenever. My husband needs to prepare for night shift as we speak, my kids go to school and I work from home. What are we expected to do in the meantime? Why is it my problem that they don't have technicians in an area that they should be servicing? Can City Power take its client a little more seriously??
