https://phabricator.wikimedia.org/p/Platonides/ says the account was created 2 months ago. Platonides, can you confirm that you added your bugzilla email address to your phabricator account, and that this was over 24 hours ago?
@platinodes, seems a ticket was made in your honor. Is there possibly a case situation here with the capital P and the emails in BZ and phab? Case mismatch is a known thing that hindered two other people.
Seems fixed. The account indeed had the email written in lowercase (fetched from LDAP?). As it doesn't allow to directly add it with a different case («Another user already has this email.») nor remove it (as it's the primary email address). Add another email, Verify, Make primary, Remove, Add with capital letter, Verify, Wait.
I recommend replacing the «If your Bugzilla activity still hasn't been assigned to you, just wait. bzimport is processing the data of more than 800 users. Please be patient.» text at https://phabricator.wikimedia.org/ with something like «Your Bugzilla activity should be assigned to you within 24 hours of linking to your phabricator account your bugzilla email (using exactly the same case).»
