No Internet

I called the Fibre Call Centre last week Friday, because my router might be faulty. As I am still working from home, I requested that they assist urgently. On Monday, I called in again as I have not received any feedback, and they then logged a ticket. Again I asked that they assist urgently. On Wednesday, I called in again, asking the same. Someone then called me back and said that they will escalate. After hearing nothing again, I called in this morning to follow up. Again I was told that it will be escalated, however there is no turn around time. This is absolutely unacceptable, and I am frustrated beyond measure. I have to keep on buying data just so that I can work from home, and it is costing me more than my monthly installment. This is not the first time that I'm struggling with this. The previous instance took more than 2 weeks to sort out. Please assist me urgently.
