It seems that the Twitter post "dimbulah singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The term "dimbulah" is not a known term in Singaporean context, and it does not appear to be a reference to any specific location or facility related to public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house in Singapore.
