Sometimes pending transactions just fail ... orphaned block or glitch ... and get returned to the sender. Have you looked at those possibilities? It's good you notified them, but too soon to call it stealing, since you haven't given them much of a chance to resend.
I did not know that, I just figured the Block-Chain is the Truth,
but if you watched my video,
there is no SENT, No Pending, , No TXID Nothing,
the record is just GONE.

If it was only marked pending on their website, then that is different than pending in the blockchain. Yeah. If there is no TXID, then that is a bigger problem.
