Cognizant Technology Solutions — Cognizant Offer Letter Not Dispatch after HR discussion

Address:

D305/102 Spoorji Complex New Town Action Area IIIKolkata 700135

Hi,
My name is Pintu Gupta. I cleared my cognizant interview and had a discussion with HR on 27-July-2022 regarding salary. HR told me that I can expect an offer in 2-3 days. I have also submitted the document he asked
It's been around 4 days and the offer letter is not dispatched yet. I tried to connect with the HR team but no one is responding to my email.
A status update on the offer letter will be highly appreciated...
