I cancelled my ticket on Sunday because I have a mistake while I bought my ticket.
So I called the call center and I bought a new ticket.
However, I cannot get the refund of the old ticket.
I used my mastercard to pay for the old ticket, but I cannot get any announcement on the refund.
Also, I checked my transcations on card but there is not a refund record.
So I wanna check my refund is ongoing or not. Thank you
