No sense of urgency by employees

I called customer care centre on the 24th April complaining about my prepaid meter box that seem faulty... start of a nightmare.. firstly the complaint was logged as power outage...later that evening..a truck and a value both with occupants came to my house only to find that I had electricity but very little as the box would not let me recharge...they told me to go the offices in Boksburg the following day.I went there ,a new reference loaded and was told to wait for the technician to come to my house to load the electricity units for me and wait for the replacement meter box to arrive in 3 weeks..when I got home the units were finished already so I had no electricity...today the 27th April I am still waiting for the technician despite several calls /follow ups with call centre.. which is also a struggle as sometimes the call is not picked up,you are put on hold until you give up or your airtime is finished.I have been told hundred times that my complaint has been escalated with no results showing though.
