Please see this page for more information on how to confirm permission, and Commons:Permission if you would like to understand why we ask for permission when uploading work that is not your own.
The file probably has been deleted. If you sent a permission, try to send it again after 14 days. Do not re-upload. When the OTRS-member processes your mail, the file can be undeleted. Additionally you can request undeletion here, providing a link to the File-page on Commons where it was uploaded ([[:File:Cartel promocional de la Enfermedad de Chagas.jpg]]) and the above demanded information in your request.
