abonnement

if your subscription was made via a mobile app store, contact the store.

if made via adobe.com, contact adobe.  there are 2 ways to contact adobe support; chat and twitter (now x):

chat:
if you have or want to purchase a subscription, 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.

twitter/x:
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.

Hey there, Welcome to the Lightroom Community. I'll help you figure this out. 

I have reviewed your account, and it doesn't show any active subscription. 

I'll move your thread now. The team will look into this. 

Regards,
