Serious Anxiety with Vox and TT Connect

TT Connect are busy updating fiber boxes in homes. Their team upgraded my box and then proceeded to continue in the area. On Friday the 14th of June their team was working on the junction box in my area and affected my line at 4pm before the long weekend. Phoned the ISP (Vox) and logged a ticket VOX**********2. They say TT Connect is the problem and logged a ticket with them 320794 (SLA is 4 to 72 hours). Several calls to VOX to explain that I work from home and have a critical meeting on Tuesday at 8am. All they can say is an area outage. I explained that my father lives 400m away from me (also Vox client) uses the same junction box, has no issues. They will escalate with TT connect… sitting here with some serious anxiety and hating VOX and TT Connect for not giving a continental damn. Disappointed.
