I had a can at Wabash Valley Armory (the original crew) when the owner died, he was the ffl holder and ATF had them refund my money despite my protests
I had friends who had class three items there and they too got refunds
I had a gun get shipped back to a seller when my FFL got sick from covid. They make a few attempts to drop it off then it got sent back. They refunded me and waved any fees.
