Swapped meters

City of Joburg representatives has been to my premises to confirm that my meter is swapped with another unit in my complex. I have opened a case last year, only for them to lose the case and say that my reference number does not exist. I opened a new case 21/04/2015 and when I call the call centre they say its pending then they escalate it. I have also been to the walk in centre twice and they say they can not do anything because its pending. I am paying someone else's electricity and if I don't pay the whole bill they will just cut off the electricity.
