if, like me, you got too carried away when about to buy your bus ticket to the machu picchu and you forgot you debit card in the atm machine, and if, you also don't know the password of your credit card because you never use it to withdraw cash and last 'if', you currently find yourself in ho chi minh-ville, then the best place to go to withdraw money is the 'anz' bank located on le duan street, next to the hard rock café and the diamond plaza. i guess it's the same in other vietnamese cities. i tried about 4 or 5 banks before going there, both big international and national ones, and anz were the only ones who were able to help me. it was also suprisingly quick, compared to bolivia or argentina. for those two countries, i also had to find a bank to withdraw cash at the counter. i'll try to find which banks it was to also put the info here, just in case you might need it. i assume that if they are the only ones who are able to provide that kinda service, they might be able to help you while others cannot.
