Per the Turbo Visa Debit Card website:
If you lose your card or believe it to be stolen, you must immediately call (888) 285-4169 to report it lost or stolen. We will cancel your current card, transfer the remaining balance to a new card, and then mail it out to you at the address on file. A lost/stolen card replacement fee applies. See your Cardholder Agreement or Deposit Account Agreement for more information.
