if they enable fiat withdrawals and leave all the other things disabled, then all people can do is withdraw.
that would not be in their best interest.
Maybe true, but I have a fiat withdrawal which I confirmed before the service was shut down, and nothing has been processed. That is inexcusable. Bitstamp is holding my fiat which I withdrew Jan 4th, 2015.
If you're in the UK, or have an address in the UK, you can file a statutory demand for payment. That starts a 21 day legal clock, and if they haven't paid after 21 days, you can start putting them into liquidation.
See:
"Make and serve a statutory demand", published by the British government. The UK has tough collection laws.
Bitstamp's registered address is:
BITSTAMP LIMITED
5 NEW STREET SQUARE
LONDON
UNITED KINGDOM
EC4A 3TW
Company No. 08157033
Act now to avoid being caught in another Mt. Gox like situation.
If it turns out that Bitstamp is OK, they'll send you your funds, and you're done. It won't hurt them if they pay.
