I'm Going Crazy Because of the Footsteps Upstairs

It's past 11 p.m. and there's a steady thumping, so I've told the management office twice and even went upstairs to talk to them in person. Each time they say, "Sorry," but a few days later it's exactly the same.

I'm starting to think I should just get the noise measured or something. Has anyone here actually managed to resolve this?
