Bad Service

I paid for the new fiber on the 13th of February 2024 and it took them 7 days to Install, after the installation I was promised that I will receive the User Name and Password by SMS, that was on the 19th of February 2024 till today (22 February 2024) I'm still waiting and the Fiber is not work. I have cancelled my previous network provider C Cell to move to Fiber. Currently I have lost R6 000 in revenue by not have internet and I have tried to Call the Vuma Fiber Support and nothing is happening as you will hold on the line more than 30 minuets and still you don't get help. Please someone help as I need to pay bills.
