I recently purchased a geocoin (TB1WJ1K ) "Wretched Skull Geocoin", from another cacher at the Wisconsin 2013 West Bend Mega Event on 8/10/13 but the owner has yet to send me the adoption email so that i can transfer ownership over to myself. I have tried emailing the owner twice and also emailed another cacher by the name of Averith who was with the coin owner at the time of sale, no answer back from either of them, what can i do so that i can get this issue resolved and get the ownership changed to me?
