I still have about 27p in my ye olde children's savings account. Every year or so I get about half a farthing in interest and think I should really actually figure out how to close the account, but I think they won't let me withdraw less than £1 or something and so it ticks on...
That's simple. Just notify the bank that you want them to close the account and give them another bankaccountnumber to put the remaining money on.
If they won't cooperate when you're at the teller's window to close out the account, just say, in an astonished voice loud enough for EVERYONE in the bank to hear, "What? You can't give me the money in my account? Why? Doesn't the bank have ENOUGH MONEY??? Is that the problem? The bank doesn't HAVE ENOUGH MONEY to let me have my money???"
I guarantee that you will have successfully escalated the situation to the highest ranking person present at the bank.
Anything they say to you that you don't like, just repeat, loud enough to be heard by others, "But it's MY money. YOU agree it's MY money. So why won't you give me my money? Doesn't the bank have enough money to cover it?"
I pulled something similar one time when I was working in fast food during high school. The paychecks were drawn on a bank right next door to where I worked. I didn't have an account at the bank because they were the slowest (and most robbed) bank in the city. I used to say the robbers were just people who got tired of waiting in line. But they were handy for if I wanted to cash my check during a work break, so I went over to do so. I spent well over 5 minutes standing in line with 4 tellers available, none of whom were meeting with other customers. By the time they got around to seeing to my needs there was a line behind me. The teller refused to cash the check because I didn't have an account at that bank.
"What?? You can't cash this check drawn on your bank? Isn't there ENOUGH MONEY here? Is that the problem? You don't have the money to cover this check?"
Gosh, golly, but a manager materialized out of nowhere and rushed that transaction through. Never saw anyone at that bank move so quickly, before or after.)
