Hello
It seems that it is still possible although it is still impossible to contact them by phone and even by email it is impossible to know my credit card number, however it told me to fill everything I could! Great !
buwaytress the office of the trustee is the phone number available on the site mt gox?
Far as I know, the trustee has responded to certain/some press comments, so definitely seems to be available for contact. I don't have any dealings with Mt Gox myself, but from communications made public by other claimants, it appears there are ways to get in touch. Have you tried looking at the recent documents posted publicly on the website? These are the details provided previous to the claims on a pdf published June 2018:
