Eskom prepaid electricity is too expensive

Im shocked at the tariff of prepaid electricity. I spent 30 units a day on average electricity. And it’s R100 to buy 30 units from all the banks and supermarkets. I can only imagine how the poor people are coping with these rates. Today I bought R300 electricity from my capitec app and I got 95 units. Which means my R300 is literally only for 3 days. That means you only get 30% of 100. I’m disappointed in Eskom and government.
