Lost all emails received since Nov 11, 2015

I just accessed my Zoho account and discovered that all my email messages received since November 11, 2015 are gone. This is not the first time I have lost information in a Zoho product. In the past i have experienced issues losing credentials in Zoho Vault. As much as i like Zoho products, if my emails cannot be recovered I'm completely abandoning Zoho and moving exclusively to Gmail. 

Did anyone else lose emails?
