Sent mail to wrong person

Hello Support I just transferred a character from Crushridge to Dragonmaw. Upon completion of that I was prompted to change his name. I did so and logged into an alt(this toon) to send over gold.

I accidently ended up typing his old name in the Send field out of habit and sent 3300gold. I sent it to a toon named Syrio. I looked up the toon on armory and it appears he hasn't been played in quite some time.

Please advise.
