Cognizant — Offer Letter not released Post HR discussion

Hello,
My name is Nagnath Mhetre.
I had my technical interview for Automation test Engineer with Cognizant on 06th/May/2022. I got a selection mail with mention necessary documents then I submitted all necessary Documents for the HR discussion, I had a positive discussion with her regarding the package and joining date and she said offer letter will be released within 2 weeks but now I haven't received any updates from the HR.
I dropped mail to her and even called her many times, but no response.
I expect at least some communication from the company side.
