Can you sue a bank for a bank error
 

Can you sue a bank for a bank error? They took money out of my account and gave it to another person with a similar account number

did they put it back yet?

If they refuse to give it back, you can take legal action.

But forget about suing them for 500 million billion dollars, that just isn't going to fly.

if it's your money it's yours

Don't trust the bank.

Don't trust the post dates either it seems.
