Not able to find my paid subscribtion account

Paying twice for the same subscription, let me think that you have taken the subscription twice on different accounts. The region is always the one that is connected to your credit card. If your credit card is a US card, the region needs to be the US. If the credit card is a French one, the region needs to be France.

But you can create multiple Adobe ID's if you have multiple e-mail addresses. So you will have to look at your e-mail addresses and check those for subscription confirmations.

Beware that Gmail, as an example, allows writing your address differently and still, it considers the mail address as the same. Example x.y@gmail.com is the same as xy@gmail.com, but Adobe treats those as 2 different addresses and will let you create 2 Adobe IDs on this. So check that too.

If you absolutely don't find your second subscription, contact Adobe customer care. They may find out what account uses the same credit card.

Important: Adobe does NOT contact you unsolicited by e-mail or direct message. If you get contacted by direct message from a person, claiming to be an Adobe employee, look at that profile and check if they bear the “Adobe Employee” marking under their name. Adobe support does not use Skype to give you support.
If in doubt, ask the forum.
