Disputing Charges On Your Credit Card Statement
Believe it or not, your credit card company can make mistakes too. You should read your report and see if there are any additional or double charges that should be disputed. If you wait too long to dispute charges, it may be too late and you’ll still be liable for paying them.
A few examples would be if your gym charged you an extra month. Or, if you cancel a flight and the airline still charges for baggage fees.
