I'm moving to London from Ireland. I made an appointment to open an account. When making that appointment I showed my proof of address to the lady (Louise in Oxford street branch) who told me it was okay.
When I went to the appointment a week later I was refused and told another form of proof was needed from my University. Then having a ran across London to get it on time I was told on my return that this wasn't enough either because it had the address written without the post code at the bottom.

*** People who aren't from your country don't automatically know how everything works... Simple communication of what was actually needed would have avoided this and not wasted two days for me! Horrible customer service.
