19 Days for an undetected Leak and still not fixed, can't even get hold of someone.

Logged call for slow leak on 3 Jul which seems to be affecting the temperature on the 2nd geyser. The plumber only came on 7 Jul, looked at the geyser and said their is no power to both geysers. Said an electrician is required.Claims agent advised new vendor has been assigned. Days passed, mailed and phoned the agent but no contact. Eventually got hold of someone else who checked and the vendor that was assigned was the same company that came out already but they said to the agent they no longer service the electricity skill. New vendor was assigned and I got a call from the company on Wed 16 Jul same day as speaking to the agent. Electrician company confirmed they will come on 17 Jul, and I confirmed I will work from home to give them access. No one came, not Thursday, not Friday and not Monday. I have been on hold for 1h20min got through to someone and they couldn't hear me apparently, I stayed on the line trying to mute and unmute on my side but it was just dead silence on the other side, even though I kept saying hi hi hi. I phoned back and was told by the IVR I am 40th in the queue. I put down and phoned again, got hold of someone and said we are transferring you to the correct department, this time and currently as I write this I have again been on hold for 1h27 still not through to someone. I need someone to come out and do a leak detection as per my original call logged on 3 Jul as I have now lost 6000 liter of water confirmed by my water meter, and check the geyser is continuously filling with water due to the leak and resulting in the temperature being so low all the time. I need someone to come and find the leak and fix it. This is absolutely ridiculous! I have now been on hold for 1h30 and cannot hold on any longer and will have to attempt again later as I have work to do and meetings to attend. I am really hoping someone sees this and comes to my rescue.
