6. Call, Cancel and Get an Effective Date
Look on your credit card statement for the customer service number to call. In many cases, there will be a separate number to call for closures or issues with your card. Be prepared for a conversation with an employee who has been trained to try to talk you out of closing your credit card. Just answer any offers or questions with your bottom line: "No, thanks, I want to close the card." Ask for the date when the closure will be effective, and clarify if there are any outstanding finance charges that will come through before the closure date. Don't assume that closure is effective immediately. If there will be finance charges, ask if you can go ahead and pay them over the phone. You can also send a letter requesting closure and save yourself some time on the phone.
