Prélèvement 59,99€ par mois sans abonnement stock

If you are still being billed monthly subscription fees, you have NOT cancelled your subscription.  If you believe you have cancelled, you should have ready the email from Adobe proving that cancellation. 

Hi,

you can contact adobe support to address the issue. There are 3 ways to contact adobe directly: chat, phone and Twitter:

Chat:
use a browser that allows popups and cookies
and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human.

Phone:

Twitter:
tweet @AdobeCare

p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative. ie, double check for an employee badge if contacted in the forums and look for an adobe.com domain in the email address if you click reply to an email. then check again and be very suspicious. any other method of contacting (or offering to contact you) is almost certainly a scam,

Hope that helps.
