Cognizant — Delay in Onboarding Pass

I have completed my pre-joining formalities without any issues. My date of joining is on 16th of August, 2021. And yet u haven't got my onboarding pass. I tried contacting the HR, he is not answering any of my calls and dodging too. I have sent an email to him and i have also sent a mail to the help centers in cognizant. No response was received.

I hope they would response soon to my queries.
