SD said the withdrawal took place but The funds never appeared.
When I try to check the blockchain it doesn't show that this deposit occurred.
Am I missing something here?
Does SD not allow for withdrawals into certain wallets?
I've tried contacting their support email to no avail. Is there anything else I can do to recover these lost/stolen coins?
Any help/thoughts/advice would be greatly appreciated.
Ask satoshidice for the tx id of the withdrawal, at least you'll know what happened. Maybe take some screenshots in case you need to prove anything (chatlogs, emails, withdrawal requests, deposit addresses,... everything like that can be usefull when you need to prove something)
