Store Credit for unsent items?!

[Europhyllia]

Was looking for some special snails that I couldn't find locally (posted in the ask a sponsor forum and inquired directly) so I ordered online from Reefs2GO.
They never contacted me but my order arrived today -incomplete.
Would have been nice if they had called and given me an opportunity to just get some more of another kind of snail rather than just send me less.
The kicker though is that they don't refund the money for the snails they didn't ship!
Can you believe it!? Not DOA. NOT SHIPPED AT ALL. And no refund!
I got store credit. As if I was going to order from them again anyway...
