To follow up my post from a few pages ago, finally my withdrawal was processed and went through. Unfortunately for me the USD lost almost 3% against the Euro in the meantime. However, after the lengthy KYC procedure went through, the withdrawal/transfer took as little time as usual. One day to change from "in process" to "finished", another day to appear on my balance statement. So generally, bitstamp appears to work.
Thanks for keeping us updated. There are some "complaints" in this threads I simply can't take serious, but after I understood what went on in your case, I was waiting to hear how it will be resolved. Glad to hear it worked out in the end, even though with a delay.
(Sorry for my initial reaction 2 or 3 pages ago, by the way. I thought your complaint was that you refuse to answer the additional KYC questions, but that was my mistake in not reading your original post careful enough.)
