Telkom fibre is pathetic

We’ve had Telkom Fibre for only a month now and have had multiple issues. The fibre disconnects randomly for no apparent reason. When I phone in to customer service they waste hours of my time, hundreds of rands in airtime, they say they can’t phone you back, most of them sound like they have no clue what they’re doing and keep you on hold for ages, most of the time I have to prompt them and tell them what to do. We work from home and it’s a crisis every time this happens because we will literally get fired if we can’t show that we’re logged in on time. I know everyone always struggles to cancel too. We signed a 24 month contract so we’re scared to cancel in case they keep taking money anyway. It feels like we’re trapped by this pathetic company. Their incompetence is unbelievable. Any help or advice on how to escape the clutches of Telkom would be greatly appreciated.
