Canceling my Afrihost subscription

I have had the worst experience with this network provider! I moved to an address at the beginning of March and requested a line to be activated in the property. There was no need for a new line to be installed, as there was already a line on the property with them. It took over 3 weeks for them to cancel the previous tenant's line even though they had already installed and activated the line. but even before that they kept me waiting for mine to be activated. I have now requested multiple times that they cancel this line and move me to a new address but keep on getting the run around by their agents who are far from helpful, they are always quick to push blame to the installation team when they haven't actioned any tickets for my line. I am honestly close to cancelling with them and moving to someone else. I'd consider Rain before dealing with Afrihost. When my partner recommended them to me, I expected world-class service, not subpar, unhelpful service. I'm on a 100mb line and it feels like nothing because of how slow they are to help.
