Vodacom fibre installation is useless

Vodacom at its worst best again. So our home fibre setup hasn't worked properly since inception. So I complain – some pleasant gentleman come to the home and so-called sort the issue out – nothing changes, in fact, now the connection is worse than before. So, I'd buy a business package – and so during last week they deliver a new router and on Friday passed a pleasant gentleman arrives to activate the router – however, the router cannot accommodate the telephones which were connected to the old router – the pleasant gentleman hangs around for more than 4 hours trying to fix the situation – but he can't – so, eventually I tell him that I need to work and that he needs to find a solution and return – well, 4 days have come and gone – I inform the installers to whom vodacom subcontracts the installation and configuration – and I inform the company/on seller that arranged the business package – no response, except for that the problem with the telephones will be escalated – and so, now I receive an SMS from vodacom indicating that the sale is complete, ostensibly meaning that everything works well – and nothing works well – I'm still on the old system – and now vodacom will start charging me for the business package as well – so I'm paying for 2 packages – it's all just beyond useless.
