Vodacom Fibre

I am a client of Vodacom Fibre of which I have been using the fibre line for many months now without any complaints. I asked to have my line upgraded to a faster speed as I work from home. This upgrade was done on 06/08/2020 and ever since my internet accessibility has been disconnected. I have made numerous calls (7 in total from 06/08 to 08/08) and every time I get told that it is a problem at Vumatel and they cannot do anything about this. I also get told that I will get feedback and to no avail No feedback either. As far as I am concerned Vumatel is a supplier to Vodacom and it is their responsibility to get this cleared. It seems to me that Vodacom just do not care about their clients as long as they can get their monthly subscriptions. I need this fibre line to do my work from home as Eskom is one of my clients and I need to be available 24 hrs a day. I think this is shocking service and would not encourage anybody to take up a contract with Vodacom Fibre
