I sent btc from Poloniex to ShapShift.
ShapeShift supplied me with an address for deposit (so I can get Ether after btc deposited):

I initiated a Poloniex Withdraw, but that took too much time, and ShapeShift closed the transaction.
I contacted ShapeShift. Asked they did. They saied they issued a refund, and gave me Transaction ID:

I then contacted Poloniex, but they can't seem to find my btc.

It looks like shapeshift screwed up and sent the refund to their own address. You will have to contact them again. Make sure that you give them a Poloniex deposit address to send the refund to.

Also, using Poloniex as a wallet is probably not a good idea.
