Dear Ismail...I think you must go and speak to HR face to face as sometimes Telephonic conversation is not enough and it shows ill manners too...i will suggest you to go to HR and speak to him in front and try to record audio, or if you spoke to him through phone then install call recorder in your cell phone and record the conversation between you two, later you can contact Human rights office(Be reminded not labor court buddy as its of no use)...best of luck
