I am confused. I assume Sarooj is female, as you said "her niece's marriage". However, you then said "for his uncle's operation". I assumed that you were correct the first time and changed "his" to "her".
However, it then became very confusing. You said "...he approached two trusts..." Did her uncle approach two trusts? Also, the last sentence is very confusing. Do you not understand why he approached them? Or do you not understand why he has not received help from either of them?
