Wipro — Unable to make changes in Embark portal for Background Verification

Hello,
I am unable to make any changes in Embark portal. The options aren't working. I can't change my gender as well as unable to modify my Educational details and personal details, I mailed to the Helpdesk. It's been 72 hours but haven't received any response. So, I request you to resolve my issue at the earliest.
Thank You.
