Send this to support: "Try Airbank instead of RB group. The account to which I asked you to deposit is actually not part of RB group anyway. You guys must have screwed up your data somewhere."
And please keep us posted. Even if you no longer want to withdraw, it might be worth trying just to see what happens as you push Bitstamp to make sense when they (mistakenly, we must assume) aren't making sense.
ok here we go - received today when I asked what happened and told them, that my bank is not part of RB group:
Dear XX,
We would like to explain that the problem does not lie with your bank, but with one of the intermediary banks.
We were also surprised to learn about the intermediary bank's internal decision to stop processing all bitcoin related transfers.
For this reason we have also notify you about this issue in advance, before processing your bank withdrawal request,
in an attempt to prevent any possible issues, which could occur while transferring your funds through the banking system.
Sincere apologies for any inconvenience.
We remain available to you in case you have any further questions about the issue or if you require any additional assistance.
Best regards,
Nejc Srečnik
so those experts recommended me to create new account:
"Please request your future bank withdrawals to an alternate bank account held in your name" (this is what I received in initial reject status mail)
and now 24 hours later:
"problem does not lie with your bank"so I'm keeping pushing them and want to explain, how to withdraw fiat from bitstamp and which banks are safe. if it is not about my bank account, how can I be sure, that they will not block my funds in the future because of some stupid excuse..:(
