Hi Nattakorn,
Thanks for contacting us.
I understand that you recently made an accidental purchase from the iTunes Store. I would want to look into any options available to me as well if I unintentionally purchased something, and I will be more than happy to assist you today.
I’ve reviewed your case and am issuing you a full refund for the unintentional purchase.
Within ten business days, 249.00 THB should be posted to the payment method used to make the purchase.
