Change last name on b.net account.

Hello. I'm looking for someone who can change the last name on my battle.net account. I can pay up to 50 euros for the service and if it costs more I can pay the reaming amount instalments. Thanks.

Can you just not login and change it?

Look up a name change template for your country, edit it, and send it to Blizzard. Good luck, and you're welcome!
