Trending @Accenture; Need suggestions

Last week I have received a feedback from my manager that I am not meeting their expectations.. I am very well working in the things what was given to me but apart from that assigned work what extra you do.. what are the other things you do. Everyone in my team does only the assigned work.. nothing more than that. And my manager told me that due to this we are putting you in PIP and I will not get the variable pay. I talked to my skip level manager and I have asked him you can track the work which I have done.. it is the highest in terms of records. I mentioned to him please release me if still you are not happy with my work but please dont put me in PIP. He said sorry I cant do anything now.

That day I put my papers.. and now again they people are harassing me.. they want my inputs in call but now I chose to remain silent. Is there any way I can deal with this situation as it is disturbing me mentally now. And my notice period is just started..
