I can fully relate. See my thread about Mt Gox keeping over $5k of mine.
They put an obscure message on their forums warning people not to deposit funds to their HSBC account. (Instead of a general message to all Mt Gox users on login or a general email to all users)
Now my $5k+ is gone and they're saying there's nothing they can do and that I have to wait 3-4 weeks (its already been a week) until the funds bounce back into my account
IMHO they should be covering the deposit and wearing the delay themselves and should have done that for the OP here straight away
For people jumping into this thread here you are what it is all about : https://bitcointalk.org/index.php?topic=74713.msg832864#msg832864
Bottom line, in your case we NEVER received your money since 20 days after the HSBC account was been closed, you try to send money to us to this account. What is happening now, is that HSBC will send back your money to your bank and you will get your money soon. we NEVER received your fund, we NEVER touched them at ANY given time. Please contact your bank to check when you will get your money back.
