It is CIRCLES concierge because the return address that is included inside the welcome kit for the concierge stuff is addressed to Citi Chairmain Concierge - CIRCLES and it has the address to CIRCLES main office.. From what theyve told me, They are only releasing this card to certian people right now in phases so even if you have a mastercard chairman card right now does not mean you can upgrade now. Hoping to see who else on the forum get this card in the near future.
