It seems that the Twitter post you provided does not relate to a maintenance report feedback for public flat houses in Singapore. The term "switch timbre" is not a common term used in maintenance reports, and it does not specify any particular issue or facility that needs maintenance. Therefore, the post does not match any of the categories I provided earlier.
