Customer service non existent incompetence at the highest levels

Been experiencing serious issues with my prepaid electricity meter. Reporting the fault 9 months ago up to date the issue not yet resolved. A few technicians were assigned over past few months, issue still not resolved they deal with symptoms instead of root cause. Last visit at department was last week meter was supposed to be fixed last night it gave in. My kids are writing exams no electricity to study while we paying for service that is non existent. I would understand if services were not paid for, payments up to date sometimes even in advance. What a dire situation to be. Not mentioning the food in the refrigerators that are spoiling.
