billing error on my Adobe Acrobat subscription

Hi,

I need help with a billing error on my Adobe Acrobat subscription, and I have not been able to reach Customer Care — the support chat window does not open for me.

What happened:

• 31 July 2025 — I subscribed to Adobe Acrobat at the nonprofit rate through Goodstack: 18.00 USD for the annual term.
• 1 July 2026 — I received an email from Adobe confirming that my annual subscription would renew at 18.00 USD.
• 31 July 2026 (today) — my card was charged 403.06 USD instead.
• 31 July 2026 — I cancelled the subscription the same day and then received an automated email saying the payment is non-refundable.
