MONEY TIP Sandra McKinnon, Cynthia E. Crawford, Ph.D., Consumer & Family Economics Specialist, University of Missouri-Columbia, University Outreach & Extension Have you ever noticed an error involving an ATM transaction on your bank statement? Do you know what to do to try and correct it? Should you notice an error on electronic transfers, which include ATM (Automatic Teller Machines) transactions, contact your bank immediately. You must contact them within 60 days after the receipt of the first statement on which the error appeared. Put your request to correct the error in writing, include your name and account number. Describe the error or the transfer you are unsure about and explain as clearly as you can why you need more information or why you believe there is an error. Include the dollar amount of the error in question. Most banks will credit your account for the amount in question so you will have use of your money during the time it takes to complete the investigation.
