I preordered a figure from them 6 months ago, paid for the figure & shipping through PayPal. They stalled until just about the day PayPal couldn’t give refunds (180 days) and then told me the item was out of stock. I asked for a refund and they said they couldn’t give it to me since it had been over 180 days (even though there were about 10 days left for the refund). I’ve sent them messages through their Facebook page & emailed them, but they’ve stopped responding to my messages completely. I’m still trying to work with PayPal to force them to give me my money back. What a nightmare..
