Vodacom's spctacular failure

After waiting from 4 Dec for the fibre to be installed, finally done today. Only to find that the sim card doesn't fit the new fibre router. After struggling to get it to fit and trying to set up the system. We once again encounter problems. The router cannot detect the network, nor can it identify the SIM. Only to be told once again to wait 24 - 48 hours. We cannot deal with this level of incompetence anymore.
