It seems that the Twitter post "grain alley singapore" does not relate to a maintenance report feedback to a public flat house. It is not clear what the post is referring to, as it does not provide any context or information about the location or issue being discussed. Therefore, I have marked the relatedness as "false" and the type as "none" in the JSON output.
