I'ts impossible to do business with this bank as a foreigner

I've spent the last four weeks and countless (international) phone calls and emails in search of someone in this organisation to update foreign contact details. Not inContact, Internet Banking, Business Banking Desk, the branch where the account was opened or (surprise) the business banker assigned to the account can assist in updating contact details.

Surely if these simple tasks can't be managed, this bank shouldn't be trusted to manage people's money. If this isn't solved within seven days I'm banking elsewhere.
