Can't unsettle/undo Voucher


I tried reopened-settle-ticket script to undo a settled ticket with Voucher. It doesn’t do anything.
I also tried settled half the amount on a ticket with voucher, and then realize there is noway to undo the voucher as how I can undo a discount. Is there anyway to undo a voucher settled ticket?


Rather than try to change a settled ticket youd be better setting up a refund system and then process a refund instead
