Internet connection

We use Fiber through Vox, for more than three years now. Vox underwriter is Vodacom. Currently we have been without Fiber since the 19th of August. I logged queries with Vox. Currently the Fiber box is on, with all lights working, but there is no Internet connection, and we were advised that it has to do with Vodacom. Please can someone just fix this issue as we rely on the Fiber at home.
