I bought from them once, and I did eventually get my order. But I would never buy from them again unless I can pick it up in person or have someone else do it for me.
As for the OP question, hard to say - you may also eventually get your order, but don't give up hassling them about it. The bad part is that you have no recourse with getting your money back, but you could talk to your bank (assuming you sent it through them) and see what they have to say. Hope it eventually works out for you as that is a fair amount of cash to 'lose'.
