Thanks for contacting eBay Customer Service about the item you listed. My name is Cah and my pleasure assisting you today.
Pongdech, upon carefully checking your account I am seeing that you cancelled this transaction and the reason is the buyer asked for it to be cancelled. At this moment, what you can do is to contact the buyer one more time and ask them to confirm the cancellation for you to be able to get you fee credited back.
I hope I was able to explain things, thanks for your patience and understanding. Thanks for choosing eBay, enjoy the rest of your day and take care.
Best regards,
Cah O.
