3 weeks waiting for a black box installment.

We have been waiting for 3 weeks now just so that they can some and install the "black box". We already have fibre in our house, all we need is that black box. They said 2 weeks maximum waiting time, but still waiting. If i phone them, very friendly people awnser but they all say the same thing.. " our technical manager have made and urgent note of this situation and will call you back". Haven't heard anything since. I understand the delema of cut backs and they have a lot of work but really?? 3 weeks waiting for a small black box to be installed. Would really appreciate it if someone, anyone can just help me.
