Do install fibre using Vumatel, they're ****ers

I have been waiting for Vuma technical team to come and install my wifi and it's been over 3weeks now ans I have not been contacted by them. I have tried sending them emails but they don't work, tried calling and couldn't go through, I'm frustrated and want my money back. The first team came and told me there are not sockets and that they've escalated the matter, to this day I have not been call for an update. Worse customer service! They call you only when they want you to make payment and they dissappear.
