Non attendance to a reported fault.

I have reported a prepaid meter fault on 2021-11-30 I was given reference number 445/2 because our prepaid meter is not working at my home and now we have been in the dark for over 3 days going for the 4th day and every time I call they say the technician is on their way, but they never come and they promised they would come yesterday 2021-12 - 02 but they didn't come. They keep giving me different stories at the call centre , either they escalate our fault, Someone is on their way, I've called so many times. My son and I need warm water, All of our food is getting spoilt in our fridge! I had to stay home for 2 days not going to work waiting for the technicians. And this is inconveniencing be cause I am now house bound because of waiting for them. How do we get someone out to our house today please? This matter is now urgent! They promised yesterday, now today, and no one is doing anything??
