Hello there
It’s against the TOS to transfer accounts. Support is not going to help you with that.
Your friend can attempt to regain access to the accounts himself, but if he has already told them he gave them away, well that’s not good to say the least.
Have your friend post his support ticket # in the following thread.

Indeed. It is not allowed to give away accounts. If someone wants to give you an account it should be in the form of an unused serial code. The reason is that your friend agreed to the TOS and not you (and also broke it).
Therefore it might be hard for support to help you.
Arise, opressed of Tyria!

You were attempting to acquire access to accounts for which you were not the owner. That is strictly forbidden, and Support will not be able to assist you with that.
