@R. B: The same thing is happening to me, too! I'm a big Twi-hard fan and ordered their Bella Swan Round Moonstone ring over a month a go and still haven't recieved it!
At first they seemed really friendly and got back to me 2-3 different times, giving me my receipt number to contact them with and track my order, telling me it would take a while since the ring was being hand-crafted. I waited... and waited. Still no ring.
And now that I've threatened to take my money back, they haven't nswered me by email.
I'm f***ing PISSED!
