Disappointed

I bought a volkano mini ups for wifi in July 2023 its November now, today its stooped working. I bought it at game jabulani mall. Instead of a refund they tell me they have to send it for repairs at volkano. I bought it because my daughter studies on line. She is writing final exams on Monday and we do not have a ups ,godforbid its load shedding. I want a refund or a new ups because it's only 4 months that we bought this
