Installation Complaint

I submitted an application for prepaid Fibre with Afrihost on the 8th of March. The router was ordered and subsequently delivered, and I received notification that Open Serve would arrange the installation. Despite multiple phone calls and escalations, we are still without Fibre, and Open Serve has not yet made any installation arrangements. My daughter works from home, and this delay is causing significant issues. I am very disappointed with the service I have received thus far.
