Refund turnaround times
Refunds from Google Play are returned to the payment method used to make the original purchase. Refunds take different amounts of time depending on how you paid.
If your refund takes longer than expected, check your refund status on your Google Pay account. If the status is "Refunded," you'll find a credit on your form of payment. If the status is "Cancelled," the order was never charged, and so you won't find a credit on your form of payment.
