Home-Connect infected with Afrihost's bad customer service

Ever since the switch over to Afrihost (14th May 2024), my Home-Connect experience has been terrible. First my static IP address that I pay for every month changed to some 100.* IP adress and is no longer static so I can't white-list it with my employer. The IP address allocated is not the same as my public IP so I cannot even port into my network from an exernal internet connection. A day later (15th May 2024) my upload speed is suddenly dropped from 200mbps to 86mbps. I've been calling non-stop to get it sorted but I get endless promises and nobody seems to know how to resolve it. Being fed-up, I decided to cancel my subscription and have to give a calendar month's notice (so it ends on 30th June 2024). This evening, after getting another call from the support agent and explaingin that he is not equiped to resolve my queries, I notice that now my 500/200 line cannot even reach 150/10 speeds. Is this how you treat your loyal customers of over 7 years? Watch how I reverse the last debit order and tell you I am not equipped to resolve your billing complaints.
