Neutral Auction House and lost money

[Gattasgraffia]

I have 2 accounts (one of them is a paid account). I needed to send money to an Ally alt from my Horde bank character, so I created an ally new character, went to booty bay and put a pumpking for sale in AH at 1000g. I logged with my other account, went with my bank character to Booty Bay auction house and bought the pumpkin for 1000g. I correctly received the pumpkind and I was deduced the 1000g. I logged out, entered my other account, logged with the character that had sold the pumpkind and the mailbox was and is still empty.
Since this is a correct action even in official, I don't understand why I didn't receive the money?
Thanks

It takes one hour for the gold to arrive.
