To provide your statement electronically, we must know that you have read and accepted the following terms. Please indicate your acceptance by clicking on the "I agree" button below.
In case of Errors or Questions About Your Electronic Transfers on your personal accounts, call or write us at the telephone number or address listed below, as soon as you can, if you think your statement or receipt is wrong or if you need more information about a transfer listed on the statement receipt. We must hear from you no later than 60 days after we send the FIRST statement on which the problem or error appeared.
If you tell us orally, we may require that you send us your complaint or question in writing within 10 business days. We will determine whether an error occurred within 10 business days (5 business days for Debit Card point-of-sale transaction and 20 business days if the transfer involved a new account) after we hear from you and will correct any error promptly. If we need more time, however, we may take up to 45 days (90 days if the transfer involved a new account, a point-of-sale transaction, or a foreign-initiated transfer) to investigate your complaint or question. If we decide to do this, we will credit your account within 10 business days (5 business days for Debit Card point-of-sale transactions and 20 business days if the transfer involved a new account) for the amount you think is in error, so that you will have the use of money during the time it takes us to complete our investigation. If we ask you to put your complaint or question in writing and we do not receive it within 10 business days, we may not credit your account. Your account is considered a new account for the first 30 days after the first deposit is made, unless each of you already has an established account with us before this account is opened.
We will tell you the results within 3 business days after completing our investigation. If we decide there was not an error, we will mail you a written explanation. You may ask for copies of the documents that we used in our investigation.
