Not to mention the disabled copy pasting.

Had a similar thing happen when my small regional bank was rolled up through a couple M&A's and I have 00s and my regional account number remained. If I ever have to call them I have to explain the situation because when I start with 0s they don't believe me.

Yup.

Here in USA, Citizen's bank, iirc a subsidiary of Royal Bank Of Scotland, has had a bug for years that prevents me from changing my password. The only way to do it is via a series of tech support calls, despite the fact that they've had an open ticket for years. The source of the problem? Can't do it on an account where the email address (not the username) has a less-than-3-character-long name, as in "[email protected]". I own a small company and setup initials for easy-to-use email addresses, and found zero problems anywhere else in the world. But these clowns seem to need "abc@..." to function correctly.

I've found bankers tend to not be the brightest bulbs in the box, and this is but one example.
