Webafrica taking ages to release my line. Pathetic support

Pathetic customer support. My fibre was cancelled with a months notice as of the end of March. Instead of discontinuing my service and releasing the line so I could move it to another ISP, they simply just stopped my service. Because the line was not released my new ISP cannot get me up and running. ZERO support over the weekend. Using their WhatsApp line us like shouting into a black hole. Someone finally got back to me on WhatsApp on Sunday (after contacting them on Saturday) saying it will take 24-48 hours for the line to be released. As of this morning (Tue) I am still waiting. I phoned and was told the same story - 24-48 hours. It's already the 6th of the month! How hard can it be to release my line????
