I also haven't received a response to my email but not a big surprise with what has happened in the Bitcoin world the last few days, I also signed up to Bips support system and opened a ticket there.
Thanks, Grimbarian, please keep me posted. I did not have a small amount at WalletBit.
Considering they took a fee on my deposit, in exchange for the wallet service; this was not free and, at the least, they owe the ability to withdraw funds.
In regards to what HAS happened in the Bitcoin world (i.e. the value of each BTC): Similar situations dealing with such large sums being stolen would lead to publicly listed addresses of those responsible and/or bad things happening.
I hope they handle this properly.
