Nightmare job - Office Assistant Salamandra Employee Review

My supervisor was very aggressive and disrespectful towards me. Alot of micro management. The job responsibilities are practically an office maid (clean up the mess your coworkers make and customers). I was dissatisfied in this position and was treated horribly because I expressed my concerns. My former supervisor is very immature and continues to provide negative reports for background investigations for other jobs I apply for. Luckily it doesnt effect me being hired.
