We hate to be the bearer of bad news, but at this time, the algorithm noted your order wasn't able to utilize the instant refund and did not generate an instant refund voucher for your order.
We are so sorry for the inconvenience this may cause you. We are working hard with the returns system to set expectations as to why it is happening.
At this time, we will have to process your return for a refund, once we have it in HQ. No worries, this will be the same amount that you would have received for the instant refund!
