Want activated fibre!

Installation happened last Wednesday. Router arrived Thursday. I have called a dozen times for activation. Someone came Monday but due to laodshedding he said he'd ask the office to activate. Yesterday I called him and he said the "office" wasn't doing anything and I should call them again. The whatsapp line replies after 2 or more hours but is no use. I called yesterday one agent said you can't help and I must call vumatel (I couldn't find a number for them online) so I called back and the next agent said that agent is wrong and they'd escalate I'm order to activate. We just want working fibre.
