Zoho Customer support - please help.  

I am using ZOHO CRM. I am trying to add an additional organizational email.  When I click "resend" to get the confirmation code email - it never shows up in the inbox.  I've tried numerous times but the email and confirmation code never arrives, so I cannot confirm the email I'm trying to add.  What can i do??  I've included a picture to help resolve the issue. 

I need help as a project is starting tomorrow.  thank you. James / james@wearegobusiness.com
