the VDSL modulates between 10 and 140 MHz.

I've read that other countries e.g. the U.K. have the range notched to exclude amateur, aviation and other bands.

Does this not happen here?

As regards specific problems, if there has been a service bulletin or similar issued to tech staff by the NBN, it would be useful to quote it's ID when reporting, so at least someone is pointed in the right direction.
