Help! Switching from Zendesk to Zoho Desk using Zwitch

Help! Switching from Zendesk to Zoho Desk using Zwitch

I am migrating from zendesk to zoho desk via the Zwitch in Zoho Desk. I was told an email would be sent to tell me how long the migration should take. However I have checked every folder and never go it. It has been in migration status for 16 hours now. In Zendesk I have 114 organizations and a total of  400 tickets and think that this time is excessive for not alot of data. Is this normal? How do I know it has not hit a glitch? Anyway I can manually stop and restart it? 

What is the typical time a migration takes? 

Using Chrome with the fastest internet speed in the world. 

Thanks for any help.
