Rediff.com India — emails in my inbox are missing

Address:

500072

Emails in my inbox are frequently missing. For example, (1) from 01/04/2017 to 07/04/2017, (2) 17/08/2017 to 29/08/2017 and (3) 27/09/17 to 13/10/17.

As the emails pertain to business like electronic procurement system (Eps), i am receiving lots of complaints from customers for not responding to their inquiries, etc. And incurring loss..

Plz. Find out the cause of this and tell me how to retrieve the missing mails.
