I just called up Chase to close my CO Mastercard, which just came up for annual fee. I wanted to see if I could transition this card to be a Chase Freedom card, which given that I had no problems with Citi doing the same thing, AA Amex -> no fee Thank You card, I expected to work out just fine. The CSR told me she could only close the card, could not do anything else with it, could not wave the annual fee, and MIGHT be able to transfer the credit line to a different UNITED credit card, but only to another united credit card. I am debating attempting to contact Chase through THEIR phone tree given that the woman on the phone claimed she worked for both Chase and UA. Anyone done something similar to this?
