user3088: I sent 3 btc from mtgox to cavirtex. The address used is correct and I was given a transaciton ID by mtgox. Yet blockchain.info shows no record of a transaction and 3 btc are missing.
I have written to both mtgox and cavirtex to ask about them - still no replies.
What can I do? How do I know if they have been stolen?
This question with an accepted answer is related - or more to the point mine is a duplicate of it:
Transaction not found

user85: Check if the transaction is in the list of unconfirmed transctions. If it's not, then the sender is at fault, Mt Gox in your case. If it is, then just be patient. It can take awhile for a transaction to get included by a miner.
