Usually when that happens the funds will bounce back into your account, the atm might have no cash in it or is simply unable to proceed with the transaction. I've had that here in the UK as well as in Manila.
I'm with HSBC and I found out by accident that I had to notify my bank 24 hours prior to going to Manila, so that my bank could put a travel marker on my debit and visa card, the travel marker unlocks the cards so it can be used in Manila or any international destination. Its one of these new security things, maybe your bank has already implimented it. So that might be the reason why she cant get money from the atm.
