Webafrica is unreachable by mail, phone and their horrible whatsapp line

Webafrica is unreachable by mail, phone and their horrible whatsapp line??? The installation was good and the line was good. The time when there was a problem, it was a horrible nightmare to communicate via the whatsApp line. And after a few days of no internet, the problem disappeared by itself. We are moving and wish to terminate the service. We gave a calendar months notice on 01 October 2021, using the official mail address: ***. Received a auto reply saying Email is so old school, we must use the "horrible" whatsapp line. Once you get past Willie-the-Bott, nothing happens for hours. So we mailed again, this time including ***, ***, ***; *** and received another reply telling us the ticket is closed. So then I called, used option 4 on the first call to speak to billing, After 9 minutes, the line was disconnected. So I called again, used option 5 for reception, and the line was disconnected.
