There is no authority to reverse anything or force anyone to do anything.
There is,
bitundo.com gives you an opportunity to get your coins back, but the transaction can only be reversed if it haven't got any confirmations, which in this case, has more than 3 confirmations unfortunately.
Sure if nothing is confirmed nothing has happened yet. Not really reversing anything just stopping somethign from happening.
And i would not consider bitundo.com (whatever the fuck that is) as an authority on anything lol.
Lets not lose ourselves in useless details.
MY statement remains true.
