Hi. I have had endless problems with them the last 2 weeks. I get told by the very clever techies that however this is the problem and it will take 24 - 48 hours. I contacted them first on Tuesday last week and the problem was only solved on Saturday at 5 o clock by Vuma after they got their instruction a hour early so please tell me does it take 4 days to send a mail or whatapp or what every system they use. And guess what happened today at 12 we came home and saw a Vuma guy at our Fibre box. We went inside and found out no internet lock a call got told we will contact you and it is now 2:25 we had no contact and we had to contact them and got told that yet again it will take 24 to 48 hours. So please can I have a manager contact me
