Fraudulent Call Alert
A recent scam has been brought to our attention in which fraudsters call clients pretending to be First Interstate or Mastercard employees asking for their PIN or social security number. Do NOT share this information with anyone. Please note, neither First Interstate nor Mastercard will ever ask for this information over the phone. For questions, please call our Client Contact Center at 1-855-342-3400.
Telephone us at 1-855-342-3400 (M-F 7:30am – 7pm and Sat 10am – 2pm MST) or write us at PO Box 30918, Billings, MT 59116-0918 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 or receipt. We must hear from you no later than 60 days after we sent 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 after we hear from you and will correct any error promptly. If we need more time, however, we may take up to 45 days to investigate your complaint or question. If we decide to do this, we will credit your account within 10 business days for the amount you think is in error, so that you will have the use of the 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.
For errors involving new accounts, point-of-sale, or foreign-initiated transactions, we may take up to 90 days to investigate your complaint or question. For new accounts, we may take up to 20 business days to credit your account for the amount you think is in error.
We will tell you the results within three business days after completing our investigation. If we decide that there was no error, we will send you a written explanation. You may ask for copies of the documents that we used in our investigation.
