Unsatisfied customer

Vuma fibre was installed yesterday and activated. We were told by installor that we have to wait an hour before connecting. We tried to connect, but got error (no internet connection). We called our ISP (Vodacom) who logged a call with Vumatel technical department. No one came back to us since then, we called our ISP again this morning and the helpful agent said he will escalate the matter. We are still waiting. I am having doubts of connecting with Vumatel, if they don't come back to us. Then what if we have a more serious problem. I am a very unhappy customer and regret subscribing with Vimatel
