Impossible to get hold of Webafrica after a billing error

This company is just about impossible to get hold of. If you phone the landline, which I have done twice, you are informed that the waiting time is in excess of an hour and that you should rather try their WhatsApp facility. If you contact them via the WhatsApp facility, you simply sit and wait as well. I was told at 11h22 today that they are waiting to assign me to a live chat with an agent and at 11h59 there was still no luck. I am not the only consumer experiencing that there is a problem to get in touch with Webafrica. Simply go on their Facebook page and you will see all the other similar complaints. The 1 star rating I gave them is too high. They should strictly speaking receive a zero star rating!
