It seems that the tweet you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "cross street exchange" is not a specific term related to maintenance or public housing, and it does not provide any information about a particular block number or street. Therefore, the answer is "False" for the relatedness and "none" for the type.
