Still waiting for refund since 20 September 2024

So, on the 20th September 2024, I paid R249 to come and install the fiber. I was told the person that stayed here before me did not cancel their membership with a provider and I must get the person to cancel. The more I am explaining to them I am in a complex with other people who has fiber and that the person who stayed here did not have fiber, the more they telling me something. Till today, I have not received any feedback email or call regarding me refund after I cancelled my request. It is now almost 2 months. POOR CUSTOMER SERVICE.
