Vodacom fibre is unreliable

I am very displeased with Vodacom fibre, I am an online teacher, and have had at least five instances of connectivity issues. I pay R700 for my fibre line, because I need a stable connection. For every connection problem I have lost interviews and classes which affects my work as a teacher. I lose money, and it also puts my job in jeopardy. I tried to call the fibre helpline this morning, but they only start working at 06:00. Please improve your services, you are putting the livelihoods of people in peril during a pandemic that already poses its own threats.
