Answer:
Look at her account to confirm the ATM withdrawals were her. If she did not make the withdrawals, she should immediately contact her bank by the most trusted way possible. Calling or going to the local branch during business hours may be best.
Explanation:
If the transactions were not made by Jocelyn and she does not have any other owners on the account it is possible that she is the victim or hackers or bank fraud. Contacting her bank notifies them that the transactions are not authorized and she will not be held accountable after the bank conducts an investigation into the transactions. The bank will then redeposit the lost funds back into her account.
