will qantas refund the fees and charges on a (JAL)reward flight

[nomad52]

I have a classic reward booking on JAL Tokyo to CDG for May 29.
Fees and surcharges totaled 17000 yen.
I can cancel for a 6000 point fee but will i get the charges back?
If I opt for the voucher (which has a use by date Sept 30 2020) does it include these fees or will it just be for the points??
I've literally spent hours trying to find the answer on their website anywhere. The call centre is only taking queries about flights over the next 2 days! I hope someone can answer as Qantas themselves are no help at all.
thanks!

When you go into the booking, you will only be able to cancel or Move dates (if available). When you select cancel, all taxes\fees will be refunded to original card. The points will be refunded less 6,000points per person.
