Acrobat Pro 7-day free trial

Last month on the 7th, I subscribed to a 7-day free trial of Acrobat Pro for a one-time personal use. I read the email sent to me stating that I would be entitled to a full-refund and no fees if I cancelled by the 28th of November. However, no invoice appeared on my account for the trial after 7 days, so I assumed the free trial automatically expired without any fees. What I failed to realise was that Adobe created a separate account with a different name and private relay Apple ID email, where all the invoices were being sent. I didn't know this happened because I have used free trials from Adobe before, and they would all appear on my invoices as shown below without creating a separate account:

Because of this, I have been unknowingly paying for this service for 2 months, and incurred an additional cancellation fee after finding out this fact. Would I be able to receive a full refund for this oversight?
