Perhaps a little help here ...

I thought my money in mtgox was lost, but I read that you can check your balance on the website mtgox.
I transferred € 500 in early bebruary, but can not see the funds. I contacted my bank before but they say it arrived at mtgox.
When I asked for clarification they say it was sent to poland bank WBS (performed from Swiss).
I have rechecked if the funds have been updated, but my old balance is still there.

What can I ask my bank to help investigation?
