Exactly! No USA banks are dealing with pesos. Forget what the clueless person on the customer service phone number tells you. Most don't understand the situation in Argentina now. They might tell you something but when you show up at the branches they aren't interested in Argentine pesos.
I'd love to hear from one person that has recently sold pesos to a bank in the USA. Let us know which branch because the ones I talked to no one is interested in it. It's too volatile and depreciating too rapidly.
