Adobe Charged for Adobe Acrobat erroneously

I subscribed to Adobe Acrobat Pro using my email address fouriepb@fourpb.com in January 2024 to solve a problem with a PDF document. I then canceled the subscription in my free time period. Unbeknown to me Adobe subscribed to an annual subscription at about the same time to Adobe Acrobat Pro using my email address pietben@fourpb.com. I only realized this month that Adobe was charging my credit card account with the amount of USD 22.99 from January 2024. They ignored my requests for a refund. The case no ADB-36848602-C8Q1 C8Q1
