Unfortunately, dealing with apartment noise is just the inescapable reality of living in Hong Kong, unless you can afford to rent or own a detached house.
I'm almost certain that the security guards will not do anything about it because they are powerless to do so and probably don't care - at all. If moving out is not an option then you might have to resort to buying ear plugs or using other methods to get even.
In Mainland China, where the apartments are probably even thinner than Hong Kong, they have this gadget that attaches to the ceiling of your apartment and vibrates repeatedly to annoy the tenants above you. It's probably illegal in Hong Kong and dangerous for the structural integrity of the building, but I've read stories about its success. You can actually rent these things from places like Taobao so you only have it whenever your neighbors act up. I've never used one and I don't recommend it but it's interesting to see how people deal with apartment noise.
However, if all the noise is coming from the apartment below you, I can think of a much easier solution to deal with that. Can anyone guess what that might be?
Anyway, here's the gadget I'm talking about:
