The given Twitter post does not seem to be related to a maintenance report feedback for a public flat house. The post mentions the band U2 and their upcoming concert in Singapore, but it does not contain any information or complaints about a broken facility or inconvenience in a public flat house. Therefore, the answer is "False" for the relatedness and "none" for the type, along with a brief explanation.
