It seems that the tweet "concourse b singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what the tweet refers to, as it is a generic location name without any additional context. Therefore, I have marked the relatedness as "false" and the type as "none" with a brief explanation.
