No Technical Support or Service Support for activation

We have app**** for Fibre from Webafrica, installation of the Fibre were completed and we received a router with the following email with regards to the router:

Good day

The router is already configured so all you need to do it plug it in, we have included a guide as well.

Our Internet, Automation and Lighting Control Specialists were paid to attend to this matter and to install the router, but we have no access to internet. It is 2 days now that we are struggling to get hold of the Technical Department or a Consultant in the Call Centre to assist us with the final steps and above all we still had to pay the Specialist. We contacted Webafrica's Call Centre on all numbers provided, we even requested for the Phone me back option, but still no reply or feedback. We require urgent assistance to have this resolved. The sign-up process was fast but with NO After Service Assistance for the activation process to actually have Internet.
