It seems that the Twitter post "spc changi singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The term "spc" could potentially stand for "Singapore Police Force," but without more context, it is difficult to determine the exact meaning of the term. Additionally, the post does not mention any specific facilities, inconveniences, block numbers, or streets related to public housing, which are the types of things that are typically reported through maintenance report feedback.
