PLNs received on 2013/12/20 after 8 weeks and 3 days.

You are right PLN is not SEPA but PLN withdrawal should have the same limits/delays as EUR. As I understand all SEPA transfers are made using polish bank BZWBK ("BZWBK 1 O. we Wrocławiu") this bank account is owned by polish branch of Mt. Gox which is called in Poland: "MT. GOX POLAND INC. SP. Z O.O." I have received money from BZWBK.

Mt.Gox: Situation as of 1st December 2013: We are currently processing withdrawals requested 3 weeks and 2 days ago
Reality:

• Me: 6 weeks and 3 days and still nothing, just nothing. And no support reply for 4 days. (PLN) (SEPA)
• BTCWorld: about 9 weeks (PLN) (SEPA)
• Abracadaver: 3 weeks 3 days (EUR) (SEPA)

Why so different delays and why Mt.Gox is lying?

Still no money and no answer from support https://support.mtgox.com/requests/162986 . Support request made 45 hours ago and no answer.

Still waiting for SEPA withdrawal to polish account. Request made 2013/10/22 (6 weeks ago) value: 423zł . Waiting for Support reply.

Wie ktoś dlaczego spread pomiędzy MtGox a Bitstamp zmienił się - jest mniejszy i wynosi ok 0% mtgox:760 bitstamp: 759

Dawniej wachał sie w granicach 10% i tłumaczono to opóźnieniem lub brakiem wypłat z MtGox-u:

A teraz? Poprawiły się wypłaty w MtGox czy pogorszyły wypłaty w Bitstamp?
