It seems that the Twitter post "rain voltex" does not relate to a maintenance report feedback to a public flat house. It is possible that the user is simply expressing their discontent with the weather, or that the term "voltex" refers to something unrelated to maintenance or public housing. Without more context or information, it is difficult to provide a more specific answer.
