UNDERSTAND REFUND TIMELINES
Adobe processes refunds within 5–7 business days. However, the funds could take longer to show on your account, depending on the payment method used.
A confirmation email is sent when the refund is complete. If you have online access to your credit account, your refund could appear earlier than on a paper statement.
