Client information from submissions on questionairre from inbox are all missing

Today I went to the Inbox to go back and get information from past submissions, and they have all been deleted and only identified by a number. I need the vital information. What happened to my client's submissions? how can I get them back?

We would like to apologize for the inconvenience caused.
