NO NETWORK and VERY UPSET!!!!

I got this below message on the 30th July, Your Vuma Reach Fibre voucher will expire in only 4 days. I then made a payment the same day, just a few hours after the payment was done, we got disconnected, it showed a red light. I then tried to call the customer care line, to my outmost surprise there is no number for it only a whatsapp chat line but make no mistake there is a contact number for Sales- yeah right best believe it. Yesterday I was on their whatsapp chat from 1PM till 4pm, that's when I got a response. I got a call from my mom that a technician came to fix and it's working. When I got home, there was no red light now but now there's no internet... so it practically worked while the technicians were there, I don't know if it's their way of creating jobs for themselves but this is inconveniencing. Schools are closed, I run a business after work, so this means I can't work when I get home. Please fix this or give me my money back and let me find a reliable service provider.

SETUP A CUSTOMER CARE LINE, what kind of business is this????!!!!
