It doesn’t happen that often, but ATM machines can make mistakes.
Once it has been confirmed that your money, or part of it, was not made available, the amount should be automatically restored to your account.
If that doesn’t happen, send us an email explaining the situation to firstname.lastname@example.org.
Make sure you have the receipt from the ATM machine you used. If you don’t have the receipt, you’ll need to identify the place, date and approximate time of the transaction.
