Fibre STILL unresolved after 3 WEEKS!

We are in the 3rd week of getting our fibre line up. After 4 different teams have been sent to our house to investigate the matter we are still without internet. The various teams that come on site keep blaming the other for incompetence with none actually solving the issue. We've escalated the issue to management and all we got was "this is unacceptable, we understand your frustration" but STILL UNRESOLVED! Considering this guys? Think again!
