Sending back the mail to request Carte Vitale more than 15 days later

Bonjour!

I received my permanant social security number in December, however I can't apply to get Carte Vitale via the online AMELI system due to the error "Votre situation actuelle ne vous permet pas de créer immédiatement votre compte ameli.".

Recently, I received a post (mail) from ameli with the documents and the form I need to send them back to obtain my Carte Vitale. However, the 15 day period they put has already passed. Also, I changed my place of residence. (and declared to ameli).

I would like to receive my carte vitale but the English speaking phone service never responds to my calls. How should I apply to get Carte Vitale?

Thank you in advance!
