Weeks of no internet and nothing gets resolved via the call centre or emails

I have been struggling for weeks with no internet, phone the call centre every few days, nothing gets resolved. Vumatel confirmed there is nothing wrong on their side, which means the issue is with Vox. On my last call yesterday they said they would send a technician out but who knows if that might actually happen, I am still waiting. Three weeks of this and now it is affecting my job because I work from home. Please send out a technician to resolve this.
