Cognizant Technology Solutions — not getting offer letter from cognizant

Address: 600043

Website: Cognizant

Hi,

I was interviewed on 23rd june 2018. Cleared two technical rounds and hr round. Provided forms to fill the details and asked to wait for two weeks to get the offer letter. Just got one email from cognizanttag and stated that your status is under review. Its been 50 days and i didn't receive my offer letter. I send multiple emails to my hr "miruthula. [protected]@cognizant.com" but she is not responding to my emails.

What should i do next? Please help me someone.
