I requested my withdrawal on April 10th and it didn't yet arrive either.
I asked support why it didn't and all they could provide was
It is still waiting to be processed due to our Polish bank`s withdrawal limits.
Do they really run MtGox on a private account instead of a business account?
It doesn't look like a personal bank account to me...
