Heavy stepping sound from upper flat

A few months ago, there was a couple new neighbours moving-in to my upper flat. It started to my painful life. The sound they made when stepping on the floor is really very noisy. It seems non-stop running in the house. Even early in the morning time and at the mid-night time. The sound seems the one is in a hurry running and very heavy steps running through the house everywhere. The sound makes me can't concentrate on doing work or sleep in the house. My head always painful. The mangement office and I have nicely talked to them to reflect my suffers. Unfortunately, it seems not improvement at all. Since they are doing in their private place, I can't do anything to stop them.


I beg anyone can give me good advice. Because of financial reason, I can't move out to get rid of them. What should I do? Thank you very much for your help!

you can warn them by first calling the police, if unsettled, then you may send them an Attorney Letter, which will likely help I think.
