On July 16 2021 itself I have successfully accepted the Cognizant Offer, completed pre Joining formalities and also received updated Doj from Cognizant. The allotted joining date with Cognizant is on 17 Sep 2021.
Four days back when I logged into my One Cognizant portal a message came that ( since I declined the offer, my Cognizant application stands revoked ) I'm not sure why I have received this message, since I already accepted my Offer. I haven't declined my Cognizant offer till date.Due to that I'm unable to sign in to the One Cognizant portal, access has been revoked. I've been facing this issue for the past 4 days.

Kindly do the needful and resolve this issue.

Thanks & Regards
