eThekwini Electricity Prepaid meter not working - No service

I have a prepaid electricity meter that have error 30. Have reported it on 16-04-2018 with reference ********** . The electricians were at my house within one hour, thought it to be excellent service but unfortunately that is where it stopped. The electricians diagnosed that there was no problem with the user iterphase as they tried a new unit and diagnosed the main meter is faulty. I was told that they would come on Tuesday 17-04-2018 to change the meter as this would give me time to register the new meter and to buy more credit as the new meter only comes with 10 units. Contacted the "Help Line" ********** 111 who told me the matter was handed over to the meter department and I must wait for them to come and install a new meter, even added that "you will have to wait for a month as you are in a queue for installation of meters" After numerous calls, holding for at least 30 minutes per call I still have no idea what is going on and to try and find out helpline gave me telephone ********** 539 for department - this number is permanently engaged. After sending message on the eThekwini Facebook have got no further to solve the problem. The user interphase used to work late at night and I managed to load some more credit but now not working anymore, tried till 2am this morning unsuccessfully. We are 2 old age pensioners and 2 special needs children in the house and find this lack of service unacceptable.
