Cognizant — offer letter not got for cleared interview

Address: Pune, Maharashtra

Hi,
I am dharnaraj, i have given cognizant interview pune i have cleared both technical and hr round on the same day. The hr people told me that i will receive offer mail within 2 weeks, but i haven't received any response yet. It's more than two months and i am still waiting. And there is no way to contact the cognizant people.
..
Seems they are conducting an interview... But not releasing offer letter.. Simply time pass.. So guys.. Do not attend interview.. Do not waste your time.
