The name of the company should be a property of a POI-like object not the building.
What I've found that would fit is https://wiki.openstreetmap.org/wiki/Tag:office%3Dmoving_company
https://wiki.openstreetmap.org/wiki/Tag:office%3Dmoving_company (as this is a low use value right now, there is no preset for it and you will need to add the attributes manually in the editor).
Written as tag-value: office=moving_company
As escada has already pointed out you should remove the designation attribute, that doesn't mean anything, and please move and correct the building outline to match the building in question (square the outline once you've moved it).
While you are at it, you might consider adding more of the facilities, buildings and addresses around your location.
