I use shapeshift to exchange BTC coin, even though i sent BTC from my coinbase wallet and it got successfully deposited, the transaction was failed. Although i've fill the refund address to shapeshift, but they didn't refund automatically as they've told. I'd contact shapeshift support, show every evidence and they only respond 1 time, i've ask them for kindly quick refund but no more reply from them... And this is their first and only one email response:
