Everyone, please take a listen!
I paid the reservation fee of 300,000 won by card at ㅇㅇㄷ and
 called to cancel, but they said I could cancel and that it was a card, so I would come to the hospital, but they said
 I didn't have to come and it would take 1-2 weeks!
But they haven't canceled my card for 3 weeks and even if I call, the manager will call me, so I tell them to wait...!
Can't we just wait for this?
But I paid by card, is it possible to cancel without a card?
