Cognizant — Not getting Offer Letter after having Salary Discussion

I was interviewed on 22nd Oct, 2021 and on 27th Oct I got the confirmation mail from CTS to submit the documents for HR Verification. I have sent the CIS form after filling it along with all the required supporting documents. I had a salary discussion session with HR on 30th Oct, 2021 and it was told that Offer Letter would be generated within 14 days.

It's almost 18 days and I didn't receive OL as of now.
