Vumatel WebAfrica Poor Customer Service!

Vumatel WebAfrica has thee WORST customer service I’ve ever experienced!! I wanted to upgrade my fibre line and was told that I need to pay for the higher package when my voucher expires which I did. Then when I check with them they still haven’t upgraded it, I was transferred from one department to the other the WHOLE day with no resolution! It’s been more than a week now!!!Requested to speak to a manger and was told that the manger is not available, there’s no number to call and can only chat via WhatsApp and the agent take their own sweet time to respond. When I followed up again today with regards to upgrading my package(THAT I’VE ALREADY PAID FOR) they now cancel my WiFi connection WITHOUT telling me and then tell me to make a payment to reconnect! and I WORK with WIFI, my whole house works on WiFi! This is now jeopardising my job since I work from home and they don’t seem to care to resolve this issue. I would really like someone from Vuma WebAfrica to give me a call to resolve this.
