I'm not a foreigner.
Some horror stories I experienced over the years.
Banco Buen Ayre (merged into some other bank a long while ago). Oay all pending balances and fees and closed my account. They draw a debt free statement. They started sending me threatening notes because they claimed I owed them like 57cts. They would not listen to me (I had all the proper paperwork, issued by them). Spent a lot of time coming and going to their office and trying to get them to piss off. Eventually payed them 60cts or so. Later received yet another balance sheet where they stated they owed me $10+. So I went to collect them. They said they could not give the money to me since I was no longer a customer and had no account. Wankers!
Banco Francés: Had an account for many years opened at the Avda. Alvear branch office (close to home) but operating from the Almagro branch office, right accross my office. Postal address worked efficiently like a charm for many years and no glitches. The day the bank has something to tell me they send the mail to my former home address and choose to disregard the postal address they asked me for and used monthly. Small problem is left unnoticed to rot and turns to more threatening letters. Alvear claims I should solve it with Almagro, Almagro says they have no issue with me. Had to go to the Main office where no one seemed to care.
Another bank whose name I can't remember: No Customer service to unsolve the fuckup they created. The internet says talk to the account officer, the account officer says talk to the phone, phone says talk to the ATM, ATM says talk to the officer, officer says has no computer access rights. Bernoulli, Murphy and Darwin all are rolling in their graves, laughing tears out of their empty eye sockets. FUBARed. Thank you very much.
Citi takes the Grand Prize. When the 2001 crisis hit us all, I was working outside BA (Pilar) and the Provincia was using Patacones (funny money) mostly not accepted within CABA limits. So they payed me with a pesos check that I could cash here. Operating in U$D, a practice encouraged under previous policies, became outlawed. I deposited my pesos check in my pesos account and it never got credited. when I asked the bank, Citi told me the balance was in my dollars account. I have no dollars account I say. You do now, they reply. Then move the pesos back to where they belong i demand. "You can not operate the dollars account, sir" they summarise for me. "Well, f#ck me rigid!" I thank them.
If you can pull it off, stay clear of them. We're experiencing a different type of "Corralito" but this is a lot more serious one. Beware!
