New Prepaid box not working

On Wednesday we loaded R100 electicity and in the morning on Thursday we woke up with no electricity and i called the call center for help on Thursday morning and they logged a call for us and they said it would be fixed after 6 hours. Thursday passed and i called them this morning to follow up and gave them the reference number and the consulted said the report said we where sorted as they came to my house on Thursday around 5 pm which is not true and also we need to visit the Zola office for further help. I asked my father to go to the Zola office when he gets there they told him to go and buy a new battery, and this machine is new but they want us to buy a battery. I am very disgusted with Eskom Service and their damaged disgusting good that they cant sustain to even work while they are still new.
