Trying to integrate Zoho CRM, Zoho Campaigns and Mailchimp

Trying to integrate Zoho CRM, Zoho Campaigns and Mailchimp

I am truly frustrated.  I want to integrate Zoho CRM and Mailchimp.  I have 500+ contacts in Mailchimp and I use their app so that people can sign up on my facebook page.  I'm trying to sync Zoho with Mailchimp so I can move all of the contacts over to Zoho.

Unfortunately, I can't tell if the contacts moved from Mailchimp to Zoho and none of my contacts from Mailchimp are showing up in Zoho Campaigns.  I am scratching my head and getting pissed! help!
