This post was a joke but I once had a woman scream at me for an hour that her account number had 666 in the middle of it. She was extremely upset that nobody warned her about this. She wanted a new account AND a refund for the entire time that the "sinful" account was active.
I should mention that her account was 15 years old at the time. The number never changed during that time it was always the same. She screamed so long and hard that they gave her a credit that essentially covered an entire year of service. I hate it here 😀
My ex wife did that with a new bank account years ago with 666 in it. I don't recall her screaming at anyone, but, it was embarrassing , nonetheless, to watch her go around and around with a banker on the issue.
