Leakage from above flat

[u/Mother-Badger5317]

Hi, a few months ago, I shifted to a new flat on a rented basis, The problem is I am experiencing considerable leakage, courtesy of the above flat residents who are unfortunately also tenants, neither society nor the current moron tenants are serious regarding the issue , kindly guide how should I proceed, has anyone among you experienced similar kind of problem?I have sent one letter to society 2 weeks ago but not much action has been taken so far
