Vodacom fibre

Vodacom has no regard for customers struggling without fibre. In 3 months they have come to repair my fibre line more then 5 times. On the 14th of december 15:00 they were here to fix the line today 27th from 12:00 i have not had any internet. We have logged calls but with no joy. They take up to a week to send someone to sort out the problem. We basically live on fibre as even our television runs through fibre. I want them to cancel the contract and take the router as it has no use to me.
