Vodacom Fibre upgrade a nightmare

I have now for more than a week been trying to upgrade my Vodacom Fibre upgrade, a process that should only take 24 hours apparently. Every day I phone the contact centre they just state that they will follow up on it and provide feedback, but this never happens. Even when I tried to escalate this, the operator was still only able to log a call, with nothing seeming to happen. Apparently there is "something wrong with my account" but this also doesnt seem to be repaired since I heard this the first time about a year ago already.
