Bad bad service

We had fibre wifi installed at home on Saturday 3 July, already paid for of course. Login was received as well as confirmation that our fibre was connected and ready for use. We have not been able to access the wifi at all. The WhatsApp bot, Willie is no help at home. Mum has been waiting since yesterday for an agent to call or WhatsApp her with assistance. No direct contact number...guess makes it easier for them to rob people of their money. Really, really bad after sale service
