Excesive meter flashing and overexpensive electricity

I have tried to contact for almost 2 weeks now. My meter flashes excessive as opposed to where im from. I recently moved and went from R450 a month to R1450 last month. And i use a gas stove, even gas kettle. No geyser as i boil bath water on the gas stove. i used to get 100 units free, and get about 300 +- units for R450, now...no free units and 198 units for R500. And it doesnt last, 1 fridge, 1 freezer, 1 led tv, 1 computer and 2 laptops. And led lights. Inside only no outside lights. No geyser, no stove, no heater. Holy ****. And I use 15 units a day....WHAT!?!
