I called the call centre to log a faulty prepaid meter call, I was informed I should go to the office to log a complaint.i did on Monday and the guy who was assisting me refused to send the technician to come check whats wrong. Yesterday my units were low, I bought electricity for R100 and got 13kw. Since the beginning of the month till now I spent about R1300 on electricity for a small house with me and kids. I buy electricity for R200 every 3rd day on a average
