I sold a few BTC on Kraken in January and placed a "USD withdraw" order on their site on January 24th.  I kept checking and it never changed from "pending", which made me suspect they had never processed the order.  After 10 business days, I posted support ticket #19434.

The Kraken support wrote back to me (only after I started posting on their Facebook page) to say that they had a batch of "malformed" USD withdrawals and it will take an investigation and 2-4 weeks to perform an investigation to find out what happened. 

I asked for a copy of the outbound wire receipt, but they never replied to that request.

How do you have a "malformed" USD withdrawal?  It sounds like he was just using words from the Bitcoin malleability bug and making up an excuse.  I am suspecting that Kraken has a serious problem in the wires department.  They may be illiquid, understaffed, incompetent, or else their bank just sucks.

I don't know if I will ever see my money again.  There is no way that any other exchange business could possibly rely upon Kraken for restocking their inventory.  They are too slow.

I would never recommend Kraken to anyone.
