brick separation on porch pillar

Default Brick pillars cracked and separating from porch
I have a house that the brick pillar is separating 3/4" from siding on the porch. Siding is plumb and lower portion of the colum is plumb. The upper portion of the column has major movement and separation from house. My question is how to report this and does anyone know what may have caused this.
I have pics but don’t see a place to post them.

When was the home built and are there other areas with this problem

Repairs required point blank.

Please learn how to arrange the photos properly.
If you can’t do that I just wonder what your reports are like.
