OP is definitely telling the truth. From reference link I copied BTC address; checking on blockchain
https://blockchain.info/address/3JM51zK1QM9sqHkD1jysBmdAamoDPXJNLrNo transactions! This is theft. Return address is irrelevant because reference link says, successfully exchanged!
Let's not use Shapeshift until resolved, their system must have a problem!
OP - they have good reputation, don't be too worried
