Well I filled out the form, full unused ticket and got this refund email from EK...
Fare refundable value : THB2705.00
Taxes and Surcharges refundable : THB1305.00
Total refundable amount : THB4010.00
Less refund Charges : THB2380.00
Residual refund value : THB1630.00
The total refund amount due to you is THB1630.00.
An amount of THB1630 will be refunded to your Credit Card.
Are they really going to drag this out and not give a full refund automatically?
