Vuma horrible resolution

I recently upgraded my line with Afrihost/Vumatel from 50/50 to 100/100 on May 4th, 2024. Although Afrihost confirms the upgrade and Vumatel indicates it's on a 100/100, my first support call instructed me to provide a screenshot from the ONT to a PC showing it's still on 50/50. Despite multiple closed tickets, my line remains at 50/50 and unstable i just use my data . They've promised someone from Vuma would contact me, but I'm still waiting. Their service has been absolutely appalling, including asking me to run speed tests on a laptop rather than a desktop, as if that would make any difference.
