Frustrating waiting - 2 weeks no fiber and no answers

I logged a complaint for fibre being down on 19th Feb. I went through all the tech aspects on the phone until eventually they said they would escalate it. I called again and was told the Nokia router is the issue and they need to now reinstall a new router and it will be assigned to technical. I was told 48hrs to support, that was 8 days ago. In these 2 weeks I call almost every day, sometimes twice a day and get told ‘I will escalate it’. I called again this morning to be told the same. I’ve asked to speak to a supervisor. I was told they will call me back. I work from home and have been without fibre now for 2 weeks. I cannot believe there is still no technician assigned and this issue is not resolved.
