Horrible service

Vumatel marketed themselves so much in my area, those of us who knew the opportunities we would be spoiled for once we had fibre signed up. They didn't bother telling us that we were going to get an ISP, fast forward we are under Supersonic. Now I need a statement to attach to a job opportunity, Supersonic says because we pay directly to vumatel they cant help, they can only generate a screen shot, vumatel call centre is only taking sales calls, they billing departments doesnt have a line to speak with. There's a cell number on a pamphlet that has the vuma details ***, the person doesn't answer, if she does shes busy, or tells you to whatsapp she will get back to you as shes the only one who can send this statement. Ive sent her everything on whatsapp, still no statement. I'm going to lose out on this job opportunity because vumatel was only interested in signing us up and nothing else beyond that.
