Hello Auttavut,
Good news, Auttavut! I have reconsider your request and was able to issue a full refund for the said purchases. Within 10 business days, ฿4,900.00 should be posted to the payment method used to make the purchase.
I hope this is all good for you, Auttavut.
Thanks and I’ll wait for your response regarding this.
