Afrihost ignoring the problem fibre line and my request to have it fixed

I have to try to get Afrihost to resolve my internet problem, which I have been reporting to them since 22.03.2021, and to date, the issue is not resolved. At this point, I feel like they are now *****ing my money. They refuse to send someone out to my house to investigate why my Fibre Line is giving problems. From eventually getting a reference number, The line has been reported with ref ISP-443048. To being said, they cannot open another reference number, but this one is closed. Now how on earth do these people work. Oh yes, they don't have a complaints centre. Really? I need this problem resolved. They hold us hostage, because they know that they are the only fibre providers in the area, and clearly, they are refusing to resolve my problem. I need someone who will investigate what the problem is and get it fixed. I cannot continue to work like this.
