Acme Data — Not extending DOJ

Hi Team

I was given a offer with DOJ within 60 days by HR(Monisha Gopal) and I was sure that my 90 days notice period will not be negotiable.

I requested her to give post 90 days only but she was like as of now you accept once not worked out I will change it.

On approaching her at the end of August she was like no it cannot be changed and you tell me is this the way the big firms work.

My BGC everything has been done and now my last working day is 30-Sep-2022 and she is not chnaging and giving me revised date.

I know still there are many positions in the same company why she is behaving so, please help me to get the revised offer letter with new DOJ.
