Can we have a response from Webafrica?

I am so frustrated at the lack of client service that Webafrica has. They have installed my router, which does not work, I have sent telephonic queries, used the live chat on Whatsapp, and they cant even find their own reference number. I am now stuck with a router that does not work and being billed for services I cannot use. HOW DOES THIS HAPPEN AND NO REPOSNSE ON ANY OF THE OTHER HELLO PETER COMMENTS FROM BUSINESS!!!!
