Signed up with Citi Diamond Preferred 3 months ago because of the promo (F1K7) that they ran which stated 0% BT for life as long as I make purchase 2 times a month. I've met all the required disclaimers and never late on my payment, but on my 3rd bill, Citi put the balance from balance transfer to a rate of 14.240%. And when I called CSR to dispute the rate, CSR claimed that the 0% rate expired in June which is not true. Citi even reminded me to make 2 purchases, on their on billing statement, to continue the 0% BT. You could googled Citi promo code F1K1 you'll see it is 0% for the life of BT. Even with this informations, CSR still come back and said that my BT rate is the Purchase rate of 14.240%. Anyway, I paid the bill in Full today and Canceled the card. BEWARE OF BAIT AND SWITCH FROM CITI PROMO.
