You say a saleswoman told you that news papers will be available in a week and you believed her. That's funny. She might have thought it was true. If the news paper publisher is not ready to deliver epub subscription reliably on time to your kobo you don't want it and can not make them deliver because of saleswoman statement.
Calibre has 26 French Language items under the News Icon you can schedule for download to your computer then transfer your Kobo. This might work for you. If you want a specific news paper call the publisher to ask if a subscription is available for your Kobo as epub.
