Fibre issues

Ever since Vumatel has taken over my fibre issues have been endless. This week alone since the 2nd my internet speeds were extremely low or i had no service at all. I call and log queries with Vodacom and they say the problem is with Vumatel. This week alone i called Vodacom 20 times and last night for a few hours again my internet worked. This morning my speed went from 20mb to 5mb and now my service is totally down. I never had issues with SADV why now since VUMATEL are in charge the problems begin. Please sort my internet out today how are we supposed to work from home when we receive service as bad as this. When calling Vumatel aswell the customer service agents sound like they asleep, they are also clueless and refuse to assist. How do you as Vumatel hire your staff? If someone behind the phone does not know how to talk to customers or solve a technical problem why are they in that position?
