Pre-paid meter faulty

Since late Sunday night we are sitting without electricity as our pre-paid meter is faulty and still has units on, but we can not put in new units. It is showing an alarm on the box and the electricity it now completely off. I have reported it 15/02/2015 just after 08:00 and when I phoned the 100th time today on 17/02/2015 at 11:05, they once again just said that they have referred the problem to the pre-paid meter guys and they take up to 48 hours to come out. Which it now already longer than 48 hours. If I phone them at night they say the pre-paid guys is only working till 4 pm, if I phone in the morning they say they work till 10 pm and definitely come out. I have been nr 4 on some or other technicians list since Tuesday morning and apparently I am now way near being helped. I just do not understand why they can not come and fix the problems we escalate. There is just no pride in work anymore
