It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The term "gxfc" is not a common term used in public housing or maintenance reports, and "citylink mall sg" is not a specific location or facility related to public housing. Therefore, the post does not match any of the categories I provided.
