Promises, promises …. No internet!

Signed up with Vox over a month ago. Was promised the line would be active in2 weeks. More than a month later, still waiting with ongoing promises of the service desk that is going to phone me??? I have a modem and router, they just need to activate the line, but no success. multiple emails, phone call, whats app …. Nothing! Stuck without internet that I desperately need for work and a company not interested in sticking to their promise.
