Fibre service

I have taken a month to month fibre contract with Vodacom in the beginning of March. It took them a week to install and it wasn't working still tool the 10th. From the start it had issues and didn't have a back up battery as per advertisment. After all these issues Vodacom had a outage the 24th March till now my fibre isn't working i logged a call the same day which wasn't done till the 25th when I got a reference no. A week later im still trying to get it sorted and when I call to cancel they telling me I must pay 12 months upfront as a cancellation fee yet it's not on my contract. Worst experience ever.
