At first, I got selected in GENC CSD offer but now they cancelled the CSD offer and transferred it to FTE(Full Time Equivalent). While I was selected in CSD I already logged in to oneCognizant portal so now I cannot log in again with same email id. I have Attached the photo. I don't know what to do regarding this portal. They only gave one day to accept the offer but I can't login to the portal
