Bad service from vuma

The fiber installation was on the 23 January 2023 and the rooter was working perfectly fine then on the 28 January 2023 it lost connection and reported the incident on the 29th and notified Webafrica that the contact details they had on my profile belonged to someone else and should update my records then was told the technician will contact me on my direct number to assist within 48-72hrs I called Webafrica and was told that i could only get assistance on WhatsApp not calls and the agent dropped my phone, I called vuma and was told that i should provide them with a ref: and gave them the one from webafrica and i was told to contact webafrica they can't assist. i asked how can they not assist yet they installed the device and if they can trace my enquiry either via my ID/Address/ the device number but the lady refused to assist and referred me back to webafrica i requested to cancel the contract and I'm am told to pay R999.00 as it is still under 12 months. i am forced to pay for non-services from WEBafrica/Vuma " technicians".
