Worst call centre agents. Worst Service Home still not connected!

My line has been active for the past 4 days after installation of the cables but still no internet they told me there's a 72 hour waiting period before they activate the line it's been way more than 72 hours and I'm still waiting, the people at the contact centre has no clue what to do as they keep saying they can't activate it manually... If I cancel and go with another ISP it takes 30 days and I already paid for this service and they saying vuma should reimburse me and vuma says they should since they're the ISP
