When the item sold and the buyer paid, that money is not instantly shown in your ' Available ' section of your Payment Summary to be able to make a refund.
If on temporary hold or it's processing, then money is taken from your bank to cover the refund when a case or cancellation is made.
Once the refund is made, it will take a dew days, but then the money the buyer paid, is released to you.
Be aware, if you cancel for out of stock reasons you will get a damaging ddefect on your account. Being a new account do not gain too many of those as eBay will place selling restrictions on your account. Worse case scenario, too many defects will lead to a permanent selling ban.
