If you know that you will leave your flat after 6-7 months. If people just above your flat like to do somo wrestling at odd times of the day.
Will you just console yourself to control your anger for 7 more months and give them a chance to miss you and pray for you when the new comers* in place of you *complain to them at least once a week to kindly sign peace treaty. Thus the people upstairs remember you with good words and prayers come out of their heart when they realize how tolerant and forgiving you were not to yourself but to them while you were around, as compared to newcomers.
Let them know who is the boss around.
Join them and enjoy watching wrestling *along with popcorn *accompanied by shrieking sounds of shouting
I have been facing a similar issue for the past few months. Thank Allah we are moving in June, Insha'Allah. We have just put up with it. My family doesnt get to hear it that much since their bedroom is not the one below where all the noise is often coming from. I thought of complaining to management but Ammi told me to let it go because we are moving anyway. Anyway, its not every night but its often enough.
If I were living by myself, I'd probably tell management to take care of it. But that's just me.
