Help Needed: Cognizant Interview Rescheduling Issue

Hi guys,

I got a call from Cognizant’s HR saying they’d schedule an interview, but on the day of the interview, I got an email saying it was canceled due to unforeseen circumstances. It’s been a month now, and they haven’t rescheduled. The HR isn’t answering my calls either. What should I do? Does anyone have contact details for Cognizant’s candidate query team?

Thanks in advance :)
