Afrihost customer service

I have had an issue with my internet for over 3 weeks now. Im paying afrihost for a 20mbs line, but receiving a 2mbs service. Every time i call afrihost, they want to try and find the problem and get back to me but never do. I called on the 12 of march 2021 again and requested to speak to a manager and got put on hold for an hour, no one came back to the line. I then realized. 1)that afrihost does not know how to deal with their clients,2) They do not know how to fix technical problems on their own equipment or they just do not prioritize faults or their clients.
