Cognizant — not received offer letter (more than 60 days)

Address: Hyderabad, Andhra Pradesh, 500019

Hello team,

I have attended interview at cognizant - hyderabad location on december 16, 2017 and got selected and i have been told i'll get a call within a week. However didn't get any calls and a month passed.

On january 22, 2018, i got a automatic trigger email from cognizant saying that i have successfully cleared all the rounds and i'll receive my offer letter and pre joining formalities shortly. However again a month passed and didn't get any mails / calls from them

I don't know what is the meaning of 'shortly' in there sense. Pathetic experience. Don't know what is going in background. Please check and update me at the earliest.
