Denied access to Adobe Acrobat Standard 2020

I made, for me, a major purchase from Dell:

Order Date: Dec 11, 2023

Part of that order was Adobe Acrobat Standard 2020

I finally have time and found the paperwork and want to access this. Apparently Dell has erased the account I set up and all evidence of this purchase. I am really mad. I paid for the software and I want access. Can this be fixed?
