If you are sure you NEVER gave Adobe your card, and you don’t have a family member who has access and did this, unfortunately your card details must have been stolen and used to buy a subscription. This is all too common. You need to treat it like any other fraudulent use of your card. Contact the card company and have it blocked, you’ll need a new card. Contacting Adobe isn’t likely to help and would mean your card details were still in the hands of criminals.
Any time you see charges on any of your credit cards that you know for sure you DID NOT MAKE you need to Contact the Credit Card Company and File a Dispute of charges. Then get a New CC number and make sure you tell your CC company to BLOCK ALL Charges on that old number.
As above this has nothing to do with Adobe. Someone, something, stole your CC number and is usiing it to b uy stuff.
