It seems that the Twitter post "omg bbbmtl" does not relate to a maintenance report feedback to a public flat house. The term "bbbmtl" is likely a shortened version of "bbb maintenance," which could refer to a maintenance issue in a building or apartment complex, but without more context, it is impossible to determine the specific nature of the issue.
