Reminds me of a bank account I had in Australia back in 1999 (I think it was Commonwealth Bank). I'd opened it as I was there travelling for a year and it made EFTPOS (early payment by card) easier and cheaper than using my UK bank card.

At the end of the year of travel, I went into the branch to close the account and they said I couldn't close it because I couldn't withdraw the remaining $2.11 because it was lower than the minimum withdrawal amount (I think maybe $10) and that I should just leave it open.

About a year later, I got the latest 6 month statement that they'd posted internationally saying that my account was now $100 ish overdrawn, because they'd started charging me a monthly fee on the account, and somehow I was just expected to have known that. The previous statement hadn't mentioned it, they'd just started charging it because they'd introduced a fee for accounts with a low balance. It took about several long international phone calls (and back then they were about $0.40 per minute, at least one was probably an hour long) to convince them that I had no plans to return to Australia in the foreseeable future, or to pay them the account fee especially given that I had attempted to close the account previously and they refused, and finally they agreed to close the account and waive the fee. But I'd spent loads in charges on the international calls, and they'd posted me a statement twice printed on heavy non-airmail paper, all because they wouldn't just let me shut my account when I originally asked in branch to do it.

25 years later and I still haven't gone back to Australia, even though it was one of the best years of my life. I'm going blame the bank for that (even though it was really just not having the opportunity to go again!)
