Trending @HCL; Bad Mouthing and Defaming

I joined in HCL 6 months back, lot of issues. Recently in the month of Jan, joined in one new team. A new reporting manager but more toxic person I met in my career, he doesn’t take any suggestions. He don’t listen to team. There was a big fight happened between us. He kept that grudge and removed from project. Now I recently moved to new project, what felt really bad is he is doing defaming and badmouthing me in front of other project people. It feels bad proving all about my work. Even though he don’t like my words he removed me, I haven’t felt bad. But talking back of me feeling bad. I don’t have any proofs to prove. Any suggestions. How can I make this issue to notice by other people. Every time am feeling disrespectful because of his talks. What kind of action I can take. Please help on this.
