It seems that the Twitter post "lcc sfc sfc2020" does not relate to a maintenance report feedback to public flat house. It appears to be a random combination of letters and numbers, and does not contain any information or context that would suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and "none" for the "type" field, along with a brief explanation of why it is not related to public housing or maintenance report feedback.
