Hello, guys

Mtgox recently locked my verified account and doesn't allow me to withdraw Bitcoin/Fiat because i used Bitinstant years ago

I have $40k USD and 100 bitcoins in my account for day trades, when i tried to withdraw, it shows
"Your account has been restricted from accessing funding options. Please contact support@mtgox.com for additional information on why your account has been restricted."

Mtgox locked all accounts who ever used Bitinstant before, i think many accounts have been locked for this cause Bitinstant and Aurumxchange used to be very popular funding options,
their statement: https://support.mtgox.com/entries/26563440-MtGox-Response-to-BitInstant-CEO-Arrest

I sent them few support tickets few days before, not a single one reply has been received until now, it seems like they are just ignoring me and buying time with this "excuse" because they have run out their FIAT and BITCOINS

Is it acceptable if they asked me to send them physically and notarized documents to their Japan office and force me to upgrade to "Trusted" level from "Verified" ? they did do such ridiculous thing to a user

Any one can help with this?
how can i contact mtgox?
do they have the right to change things like this overnight?
