Am I fudged? Accidently send to wrong people..

So, I accidently send some stuff (not gold) to one of my fellow retired guildies because of the auto recommendation on mail. I tried using the restore mail but it says its claimed when indeed he is not even online for 5 years. Tried aswell contacting the blizz support but no luck. Do I get back the item if its not claimed? or is it burn for good?
