Moving out into another basic room is fairly easy. But singles are high demand. They’re typically full and waitlisted. They most likely do not have one available for OP to move into, hence the denial. There’s nothing more they can do right now bc the school will not (and cannot) force someone to move out of their room to fulfill the accommodation. They can try next semester to see if a senior had one and graduated, someone transferred out, or just wait for housing application for next year
