Solo solicite Lighroom y ahora me estan queriendo cobrar algo de adobe stock, aunque yo nunca lo solicite al plan y ya lo cancele hoy. Pero hace un momento me quisieron cobrar devuelta algo que ya cancele y que nunca quise

then cancel your stock subscription. 

make sure you're aware of the cancellation terms by selecting your plan type (at the top of the page here), https://helpx.adobe.com/manage-account/using/creative-cloud-subscription-terms.html 

for info on how to cancel your subscription, this page describes the few steps involved, https://helpx.adobe.com/manage-account/using/cancel-subscription.html

if you want to cancel but are unable to follow the steps described in the "how to cancel page", you probably have a payment error that you need to repair before cancellation is allowed, https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html

Here is the technical forum for Lightroom Classic.

You better post your question in Account, Payment, & Plan | Adobe DME
