There is no refund for an e-ticket when it is downloaded. You may have used it, it cannot be seen or checked, and in that  case you’d have a refund and travel free.  NS does not refund an e-ticket for that reason.

even if its bought for the 19th ? i bought it for the 19th so i havent use them

No, because you can still use them the 19th, even when you have a refund. Your refund cannot be seen and it is still a valid ticket for the 19th. You can normally enter the station with it, even with gates. With a refund it means free travel. NS is not that foolish.
