Cash power device is broken. I type 3,6 and 9 on it

Since Sunday I don't have electricity. I reported even went to the Cullinan branch got ref number *** on Monday. You can't even talk to the Eskom official you stand outside and can only talk to the security at the gate. I'm frustrated I'm a single woman with 2 kids in a dark for 5days. All the food I bought is rotten. I have run out of cash flow for takeaways everyday. I don't know what to do anymore
