Shapeshift is not a scam, although they have a negative trust rating it is actually not them just receiving deposits and not sending out the exchanged altcoins, but rather regarding the transaction fees that they charge which imo is unfair as well.
It's only a small amount and i doubt you'll get scammed by them. Although time is a factor here, you may be waiting for a while before you receive any sort of tangible asset into your wallet, even though they have promised to send it ages ago.
Let us know on the updates.
