Serious Issues at Afrihost - Severely Undertrained Staff

Where do I start... My fibre line went down for 3 days... Due to the ONT apparently being out of date. I got a New ONT "Upgrade" installed from TT Connect and since then my 75mbps line has been running an upload speed of about 12 - 20mbps. This was in July... For the last 4 weeks I have spoken to maybe 15 consultants, Sent emails, spoke on whatsapp chat, spoken to people in the call centre, spoken to consultant on My Broadband forum... I have reached out everywhere where I could possibly do so and I am met with SERIOUSLY uninformed, untrained people who have no idea how to communicate or listen to a customer but rather have a stream of generic responses to troubleshoot (You could do the same thing with a FAQ page) My responses and very detailed explanations have been ignored over and over and over and I am sitting here 4 weeks later not one step closer to a solution. I am baffled and defeated that such a big brand has such shocking service and knowledge on their product. Nevermind the sheer uninterest of people who just want to get you off the phone. I have been told to do the same troubleshooting tests over and over which I must have done 20+ times now and I am ignored when I say I have done this numerous times. I have tried to be patient and understand the need for these tests but this is not ridiculous and a complete waste of my time when its clearly not finding the issue.
