TERRIBLE, TERRIBLE Customer Service from Vodacom Fibre

I have ordered a VOIP phone on 11 December last year for my Vodacom Fibre service. After numerous calls and bad reviews on HelloPeter, I eventually received my phone on 21 January 2019. After battling to get hold of the person working on my case, I was told that the line had to set up and the phone had to be configured. Nothing is working still, despite me calling on Monday 28 January and the operator promising he would send an escalation email to get the phone configured.

I phoned again today and the operator said the phone has still not been configured and she would follow up. I'm not holding my breath that anything is going to happen...

This is extremely terrible service! How do I get them to do their work? It is extremely frustrating to deal with Vodacom Fibre. I feel like kicking myself for signing a 24-month contract with their Vodacom's Fibre service!
