Almost never buy the refundable fares but wondering the answer to this question:

If I use a WN voucher to purchase a refundable fare and I have to cancel that ticket, will the refund go back to the original voucher, or will the refund be issued as a new voucher or will it become a ttf in the name of the named traveler?

Couldn't find an answer so tossing it out to my friends here.

TIA.
