Vumatel dropping the ball in Pretoria

We stay in Moreleta Park in Pretoria and we've been without fibre internet due to Vumatel's issues three times in two weeks. The first time we were off for two days before the internet was returned. Each time we are told to contact our ISPs who can only inform us that the problem lies with Vumatel. Honestly, we pay such high prices and we need to work from home. It makes it impossible to get any work done. So fed up!
