Changing username didn't make it available

Vinícius_25ok77

My question is similar to 1257161. I have two Bitbucket accounts (say, A1 and A2), and since it isn't possible to merge them, I moved all of my repositories to A1. However, in order to be consistent with my other website usernames, I tried to keep the username of A2. I changed A2's username to something else hoping that it would make its previous username available, but it didn't: when I try to change A1's username to the old A2's username, I get an error ("an account with that name already exists"). I waited a few months and nothing has changed. It doesn't even let me change A2's username back to the previous one (which would be good as well, since I would just move my repositories to A2 and keep using it instead). 

Is there something I can do to get my old username back, in any of my accounts?

Thank you.

Are you attempting to change a username or workspace ID?

Here is the username change page: https://bitbucket.org/account/settings/username/change/

Usernames are not important because they are not part of any URL in your Bitbucket project. The workspace ID, however, will show up in the URL.

It seems like you may need to change the workspace ID of A1 to something different, and then change A2.
