Cognizant Technology Solutions — Offer letter not received (Jasper Report)

Address: Pune

Hi Team
I am Devendra Sharma. I have attended technical interview (for Jasper Report) and got the confirmation mail saying that I got selected and on 09 June 2021, I have received the mail to submit the CIS candidate information sheet to proceed further.

Later on, I got a HR call and HR confirmed that they will release the offer letter in few days but it's been more than six month now .
I still haven't received my offer letter and also no update.

please help me in getting the offer letter.

thanks in advance.
