Cognizant — offer letter not released and no response from the hr

I have attended interview for msbi on march 9, 2019 in mindspace, hyderabad and was selected and hr informed me that offer will be released in 10 days.

After few days i got that application is on hold and needs 1 month time, but even after a month there is no response. Few days back i got a mail to submit cis form and i did it.

But i did not get any mail/call after that and also there is no response from hr even after multiple follow up mails.
