An Aternos Server has disappeared and I have not received notification nor does it appear in the backups.

Hello, first of all, thank you alternate for letting me use this server service, second, that I create a kind of server/school to teach my friends to play minecraft, but now I don't see it, apart from the fact that I had a backup of that server and it has practically disappeared. Could you give me an answer or something? Another thing is that they have deleted an aternos account, his name was Kevin Gaeta. Thank you and good afternoon.
