This topic comes up over and over again. Their bank is Unicredit Slovenia. Maybe not my ideal idea of a bank either, but probably better than the (formerly) state owned Slovenian banks.
Anyway, the point is Bitstamp decided on that bank, and that is that. It's clear they won't change that part of their system, so you either accept that element of risk or not.
The lack of response/updates and general feeling of creeping up delays however is something they *can* quickly fix, and there's no excuse for not doing so (by hiring some more staff).
