In general, refunds are applied starting with your final payment and working backwards to earlier payments.
Full Refunds
If you have returned an order in its entirety and the full amount of the order is refunded, any upcoming payments will be cancelled and any payments you have already made will be refunded back to the card you paid with.
Partial Refunds
The same principles apply if you’ve returned a portion of an order and received a partial refund.
