Nhk has sent the cancellation letter, will nhk send back a notice of successful cancellation, or will the money be directly returned to the credit card? I paid by card.
Yes, it is a normal way to return by the same route. However, some banks' credit cards do not support this transaction route. Therefore, I suggest you consult the credit card issuing bank. In addition, if there are other ways for nhk, you'd better say hello in advance to avoid unnecessary disputes.
