Horrible service and information

I requested a fiber router from Vodacom and their sales consultant arrived at my home on the 14th of January 2023, I informed the consultant that I needed this working by the 18th as on the 20th I'm starting a new Job and I'll be working from home. The sales agent informed me it is doable, signed the contract and on the 18th the router arrived. I have an existing Openserv ONT and the sales agent said with that they can fast track the activation since I have that ONT at my home. So on the 18th I insert the router, today is the 25th and it hasn't worked since it's installation, I've spoken to a number of team leaders, I was informed I'd be called back by a consultant from Openserv to help link the devices which never happened I've sent a number of emails with all the information they needed from me. I was informed it would be working by Sunday the 22nd as the activation takes 24 to 48hrs, we are on the 25th of January and it's still not working, I contacted their team on Twitter on the 24th of January and I was informed I'd be called back, I'm yet to recieve that call. I received 20gigs from them to atleast try and work since they were failing to connect the line. I requested the cancellation departments contact number from their twitter team they said I'd be called back and they didn't call me back nor supply me with the contact details for their cancellation team. I called their call centre and requested a cancellation. I hope they don't bill me for something I have not used. I hope they cancel it in the 48 to 72 hrs period. I've received horrible service, they didn't have answers as to why they could not connect me.
