What reason do I pick for a refund due to an unclaimed package?

[bentley65]

I am refunding a buyer that did not claim a package and it came back unclaimed - return to sender. This went to a USA buyer. He has not asked for a return or refund. I just want to refund all his money asap because I  now have the item and from what I can see I have his money. When I look at the refund form no option is there for a reason as unclaimed package. What should I pick as the reason?

I did message the buyer and no reply yet. However I just want to refund and then sadly block him. I don't want to sell to a buyer that doesn't pick up their parcels.  I don't want to ship again to this buyer.

Thanks for any help.

In November 2021, I went to the US to pick up my mail and there was a parcel that was returned June 2020 (17 months ago).  The buyer never contacted me nor has he purchased anything else on ebay since June 2020, who knows he might had died.  Unless the buyer contacts you, I wouldn't do anything.
