Cancelation and new order for fiber connection

Web Africa is the worst when I comes to customer service. I have been trying to cancel and reorder a new installation for fiber for over three weeks now. My frustrations are beyond and above tolerable. I use wifi for work and school purposes and I moved homes. I have been trying to communicate sending emails, texting on their whatsapp number, using their website and calling for almost three weeks to four with no assistance at all. Their whatsapp is not helpful, the website is not helpful, they never answer phone calls which you have to hold for hours and still not get connected. Their consultants don't call back and their whatsapp consultants keep cutting me off before I can get the relevant communication. I am trying to avoid double billing this month end and also hoping to be connected because I have to work to do classes to attend. No alternative solution or advise is given and I'm already going over budget to get data for my work and classes for school. I am highly stressed and very furious with the kind o service I have been receiving. All I need right now is a way forward and to confirm if the installation has been ordered for my new address, to find out when it will arrive and how do I make payment, and if the cancelation has been done for the old address.
