Cognizant — Offer Letter does not received post discussion of annual CTC

Hi

I have been interviewed on 23rd April 2022, and got selection email on 29th Apr. Post submitting CIS form and discussion on CTC. HR confirmed we are good to hire with the discussed annual ctc. After two weeks i haven't received any offer letter over the email and try to reach them but no response. On date 18th may i again gave them a call regarding the issue of generating the offer letter, they told me they have some internal screening where your offer does not make a stand. It's so unfair that they haven't done any negotiation nor they are releasing my offer letter. Please help me with this issue.

Thanks,
