Need to restore a deleted contact list

I was trying to post data from Zoho CRM to Zoho Campaign manually. I was able to do it but it saved the pushed data to the wrong list making that list over 800 contacts. I need to restore back prior to the manual push. Also I'm trying to download contacts from a previous correct campaign but after selecting first name. last name, email and mobile, the download only shows the email address.

I'm not able to share the document either as a CSV or TSV to show you what I mean.

Desperate!
