Cognizant — offer letter not received since more than a month

Address:

Pune, Maharashtra

I attended the interview at cognizant pune location on 6th october. All the rounds and hr discussion was cleared by me and the package discussion was done. They told me that i will be getting the offer letter within a couple of weeks
However, its been more than a month now and i havent received a single email from them regarding anything.
I contacted the hr a few times via email but no response was given.

Pathetic from the side of such a huge mnc. A huge disappointment from a company i was looking forward to work with.
