That's probably not Adobe who sold it to you. If so, call sales with an order number. You can reach them with your name and password and search around for sales, and they can be in a chat too. But make sure it's a real Adobe receipt before calling or chatting.
You might have had a scam deal made to you. Did you get the key for the download? That usually comes in an email. If not, it's a scam. If so, try the download again. If you think you have a good key, there is another download in another place then use the key to register.
Best Resolution: Call your bank to reverse the charge explaining you never bought the product. For a cancel-fee on a credit card, usually around $35.00, they will reverse it. The bank reverse is much easier even if it costs ya. It doesn't damage credit. Then try again with a real Adobe seller.
