During mco time I hear chair dragging sound in middle of night
Every time I call the guard to sound this fella. this fella will drag one more time then stop
But recently this fella getting more malicious
Drag chair late at night 1 am
I confronted the fella but the wife denied say they never drag any chair
Then got new sound they purposely drop something very heavy on the floor
I really marah I take big stick and hit the Ceiling
I am thinking of buying a basketball and hit the ceiling too

But in mean times what can I do ?
I lodge report with maintenance office
But they sort of deaf ear now
Should I be more aggressive ?
Would this provoke the upstairs to drag chair even more ?
I have some chair felt gliders bought from ace hardware
Thinking of passing to MO to pass to this fella
But they not 100% stop chair drag noise
