Non-existent support/service from Vox Telecom

Vox Telecom's support and service is non-existent.

I have been trying to contact Vox for the last 4-5 days. I need to report a loss of Internet connection on a fibre line.

I have phoned their Kimberley office on *** several times. The phone is never answered, except by an answering system. Nobody has ever returned my calls.

I've also called their two "support" numbers on a number of occasions:- Consumer Support: +***0 Business Support: +***0

In spite of leaving several requests for them to call me back, nobody has ever done so.

I've emailed ***. All I get from that is a reference number (eg VOX***3) but nothing further.
