Process: EmigrantDirect's missing "delete" button

I wanted to remove a link between my Emigrant Direct savings and another bank account that I closed several months ago. So, I signed on (username, password, last 4 digits of SSN) and didn't know exactly what to look for, but assumed it'd be along the lines of "Accounts / Funding / Delete"

Here's the screen:



With no "delete" option in sight, I wrote to customer service... received this reply this morning (e-mail notification of "important message", then username, password, last 4 digits of SSN to sign on):



It feels more and more like organizations publish instructions that "seem" correct, whether or not they really are correct. In this case, there's no delete option, but the customer service rep presumes there should be... or it's missing from my screen due to some other business rule that nobody at the back end has told the front end about. In any case, it's a process failure on the bank's part... two people spent a lot of time working their way toward ultimately useless, redundant instructions.
