Poor fibre internet connection

I have not been having fibre connection for the past three weeks since December 2020. When i call almost everyday they make me do the same trouble shooting procedures that do not yield any results.

After the first two weeks, they escalated my query to the 2nd line support team and they said a technician will call me and come to site to investigate and fix the issue but no one has called me since.

This is a serious inconvenience for me as this is affecting not only mine but my entire families productivity.
