Being ghosted by an ISP

I am absolutely stunned by how poor webafrica's customer service is, in particular because I'm a new customer and I would have expected them to at least pretend to be interested in me before my router has even arrived.

I submitted all my documentation immediately after placing my order and never heard back from them. They blew past the delivery date so I logged into my account to check, and discovered that they'd had an issue with my RICA status and hadn't bothered to get in touch. Now I've had an open ticket for days, I've tried to contact them by phone, by Whatsapp, by Facebook - nothing. No response. I can't believe I'm saying this, but they're actually more disappointing than Telkom.
