Webmail - Vanished (Deleted) Inbox emails

I am writing this on behalf of my daughter (also a Cox Customer).

While in Webmail, she selected and deleted 40 emails from her Inbox. Immediately she noticed that all emails from her Inbox had disappeared.

- She immediately called Cox Support.

- She was told that all e-mails were moved to her Trash folder, she should access her Trash folder and move all emails back to her Inbox folder.

- She did that; however only, e-mails from 05/22/2021 to date were retrieved.

- She called Cox Support, the associate tried but could not help her. In the end, he advised to obtain support via Cox Complete Care.

My question is will Cox Complete Care have access to Cox mail servers and thus be able to retrieve her e-mails?

Best Regards.
