Cognizant — email id updation

I got selected in congnizent i was fill hr form but with small mistake i was weitten wrong maiil id [protected]@gmail.com instead of [protected]@gmail.com so offer letter was sent to wrong id. Cognizent team called me for the joining. I tried to explain him but he disconnected my cal without listening my words. So kindly update my mailid from [protected]@gmail.com to [protected]@gmail.com and resend my offer letter to my correct mailid
