Vuma ***********, uncontactable

My internet has been down since last week tuesday, 13 April. Webafrica said my payment did not go off. So I remembered I received a new card from my bank. I promptly updated my card details on the webafrica website, on my profile and on the Payfast site through which I make payments. Nothing happened. Vuma did not collect payment nor Webafrica. Several frustrating chats on webafrica WhatsApp line and all the agents can say is that I must wait on Vuma to contact me. How long must I still wait for Vuma??? Other companies who noticed my April payment did not go off sent me an email with a link to update my card details. Within seconds of me updating card, their payments went through and my subscription continued. But NOT Vuma....how hard is it for an Internet company to set up a link for payment??? I need the fibre/ internet for my work. It's been more than a week without. Vuma has no channel where one can contact them, no phone number, email or website. Very unprofessional.
