I recently got an email from Chase saying that they were going to close my Slate account due to inactivity if I did not begin using it again. I got the card for the balance transfer offer and it served its purpose and now I just don't have a need for it. Should I just let them close it? I am not worried about the utilization ratio because I have virtually no balances on other cards. I think I would take a ding on the average age of accounts but not sure how much of one. Anyone run in to this issue before?
