It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "bawangchaji" is not a common term in Singaporean English, and it does not appear to be a word related to public housing or maintenance reports. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house in Singapore.
