It's great that you took one for the team. Thank you so much for that. It should make it obvious that it's actually a Citi and not a partner issue.
Maybe you could reach out to one of these people on LinkedIn?

Or maybe email them at
[email protected] or so (guess their email address can't be too difficult to guess).
Hopefully they'd have someone into this.
