TFed’s fraud alert service is operated by Fiserv, who is operating on behalf of TFed. If you have been contacted by a Fiserv representative and do not wish to provide confirmation of your transactions with them, you may contact a TFed Representative at (508) 824-6466 during regular business hours, otherwise your Debit Card will be restricted for use. You are responsible to keep your address and phone number updated with TFed at all times. Data rates may apply. There is no service fee for Fraud Alerts, but you are responsible for any and all charges, including, but not limited to, fees associated with data usage, imposed by your Carrier.
