I called in an attempt for Citi to wave the annual fee for my Citi AAdvantage Visa at the end of August, and it was granted.... well it was granted in the form of a $85 fee credit, but with annual fee being due in September it canceled the $85 charge that posted.
Citi also gave me a statement credit in July for my Citi AAdvantage Mastercard.
Yes, I realize I could attempt to churn, but at this time don't want to have my credit score take a hit.
