The buyer has to send you a request to cancel, it is in MORE ACTIONS. You accept and if they have paid refund.
If they have not paid then you just get your selling fee refunded.
If they have paid you still get your selling fee refunded, but NOT the paypal fee.
This sort of buyer is a time waster and can also cost you money, so add to your Blocked Bidders List, as you can do without their "custom".
