Hi all.
I got a handyman round to move the position of a shelf 5 inches up the wall. We used the same kind of wall plugs as previous and the same load went back on the shelf. However the shelf now does not want to stay on the wall. I have a new build plasterboard wall and the shelf is a floating shelf approximately 5kg in weight and 3.5 foot long. It has two wall bracket supports (one pictured). Any ideas what the issue is and how to remedy please? Used screw in type metal plugs (as picture), wondering if toggle plugs would be better but existing holes are probably bigger. Also seems that the handyman drilled in at an angle which is maybe why plug pictured in wall is loose.
