I've had a certain credit card since 1993, but I never use it. I got a letter from the company today stating that my account would now be charged a $60 annual fee unless I use my card for $2400 or more in annual purchases. I don't plan to do this. I'd like to call and tell them to close my account, but I'm hesitant to do so because it has such a long history. Any advice? Thanks!
