So I've purchased a new house, and when I went to plug in my router I noticed the ONT screws have come out of the wall and the entire thing is being held by a single screw. The box was also installed using wall anchors into Gib instead of into a stud.

So question - how do I screw it back in? Is it a $331 + gst Chorus call out fee? If so, then I may as well relocate somewhere else.
