Sorry to say, but again in defence of fencing contractors, they would not put up a fence without the pegs being in place, and if the pegs aren't in place, they would make the owner of the land reinstate these prior to construction of the house. This would include you aswell. If you believe the boundary pegs to be in the wrong position, this is something you could put back on the Developer rather than the builder.
As both your Supervisor and their Supervisor have met and have resolved the issue, I doubt there is anything else you can do, other than approach your neighbour to mutually replace the fence. As they appear to have complied completely with the fencing act, there is no legal action you can take and if you were to touch the fence you would be committing a crime and liable for charges.
In all honesty, I only say this out of concern, Tread carfefully. These are your neighbours you are battling. There is nothing worse than living next to people that you can't get along with.
