I got a reply from them after reporting an issue, to my email.

The message contains an URL to the case where I should be able to add more comments.

The URL is like http://support.bitinstant.com/customer/portal/private/cases/xyz

(xyz is the case number)

When opening it, it throws me to the main page: http://support.bitinstant.com/

Is this some temporary problem on their side?

I also tried to reply by email, but got no response for that.

Any idea what to do next?

The problem is a wrong (invalid, so the funds wont end up on someone else's account) destination account number in a transfer I made.

Regards,
David
