Cognizant — Did not receive onboarding email

Hi Team,

I received offer letter on July 22 and ever since then I did not receive any emails to complete my onboarding.

I was asked to check the for email in Spam folder by the HR but I'm afraid, I couldn't find it there too.

However, the team had been saying that they are trying to check but I did not receive any further information.

Please help me with the issue as my last working day at my current employer is August 25 and my joining date at cognizant is August 27.
