Hosting gone downhill this year

For a long time, I have been a paying customer to Afrihost Hosting with many a domain that I host there. The past year, things seem to be going more and more downhill. in the past, I would log a support ticket and get a response at most 24 hours later. Most things I contacted them about was resolved almost instantly. Then 2017 seemed to happen. I logged a ticket, took them nearly a week to respond. Thought "ok, maybe they just got a little busy. They giving me great service, so its fine." Then this year happened. I went to start my redesign to fit in with the latest trends when i noticed one of my domains seem to no longer exist on the internet. I logged a ticket earlier this month, contacted them and responded to them multiple times and yet, my domain is still down. With every contact, the only response I get is "it will be resolved within the next hour" for the past few weeks. As someone who relies on my business being online, this is unacceptable and increasingly annoying as over-promising and no delivery is not how one conduct business. The only team that seems to respond instantly is sales when they think they can sell you something. Is this really all you have become Afrihost? No service and all sales?
