Technical Mail supposedly returned but does not arrive

[Letalstrike]

I sold the item Hand of Edward The Stranger and the player who bought it from me wanted to receive it through C.O.D and when I asked him if it arrived he told me that he had returned it because he had dropped one and he returned the email, this happened more ago 12 hours and I have not received any returned emails and I am worried that there has been some problem

The name of the player to whom I sent the email with C.O.D is Kinsmen

Don't worry, it will return in 3 days at the latest. If you didn't make a mistake and set it COD.
