It seems that the tweet "k bar yishun singapore" does not relate to a maintenance report feedback for a public flat house. The term "k bar" is likely a misspelling or a non-sensical term, and "yishun" is a location in Singapore. Therefore, this tweet does not contain any relevant information for the given prompt.
