Cognizant — Offer letter not issued

I have given an interview on 07-AUG-21 or Informatica ETL developer, On 27-AUG-31 I got mail for hr to submit documents along with CIS form.
On 31-AUG-31 I got a call from hr for a salary discussion. At end of the discussion hr told you will revceive the offer shortly but then no call or email from hr or cognizant. Now I am not sure if i get the offer letter or not.

Thanks
