Cancelled my membership without Authority

Had an incident at gym with a member that let to a fight.Kabelo the manager then cancelled my contract without me knowing and refused me today to use the gym whilst the lady Paulina at Head Office gave me access since Kabelo had not even informed head office even though the incident happened four days ago.I am disgusted by his ******** behaviour and should be fired since he is *********. I will now sue gym for Breach of Contract
