It is your choice, but if received within the last 30 days you open a not as described case to get a refund.
If over 30 days then contact your payment provider. In any case a decent seller would be able to help and refund through ebay up to 90 days.
Ebay provides the means of getting refunds within 30 days, or payment provider can also get a refund. It seems foolish just to blame ebay and let the seller off the hook.
It is on every listing right side use it if appropriate.
