Thank you for the update, @talented_mentor7508.
I understand how frustrating it can be to discover you've been charged for a plan you believed had already been replaced by your Creative Cloud subscription.
I can confirm that your Creative Cloud Photography plan was successfully canceled today. Since refund requests require Adobe's review, you'll need to contact us directly for assistance.
I understand you've mentioned that chat has not been helpful. However, I am unable to find any prior support interactions for this issue, so I recommend starting a new chat session with our support team to review your cancellation and discuss any available options.
You can contact us here:
