<prompt> Human: So today my sister called me asking for advice on what to do if there are transactions on her card that she did not make. There have been two transaction from PA-VISTAPRVistaPrin totalling to around 100 dollars. I heard in the past that if you tell a bank your identity has been stolen they will make you prove it. So what should we do? I have already told her to lock her card so that it can not be used. Thanks in advance. Edit:The money is being returned to the account and she is going to set up a new account and transfer funds to it for online use. I know this is not a financial question but i dont know where else to ask. We called the company that the charge was from and they told us the name of the guy who placed the order and that he has an account with them, should we make a statement with the police so they can try to find this guy or is it a wast of time?  <response>: Tell the bank. Its the merchants responsibility to prove the validity of a charge.
