Vodacom Fibre no service

My fibre connection has been up and down intermittently dropping to 0.2 MBPS for a long time. I cannot conduct MS Teams meetings because the network is worse than a 64K modem from the 90's. All I get told is to reboot it, which I did, 10 times already and it is still the same. So Vodacom is sending out a technician to install a new router (which I don't think is the problem). There is just no service, there is no communication with the paying client, just take my money and you are on your own. This has been going on since Monday 3 May
