I hope you paid with a credit card...I only use AMX when I can as they always refund my monies and I really do not know if AMX or the suppler eats the costs, I just get ALL my monies back and sometimes get to keep the item(s) as I never heard back form the vendor(s)...kind of my pay for all the troubles I guess...

Even if you used any other Credit card, call them and say you want the monies refunded...I always tell them what I have done...how many e-mails, what the vendor has said and or done....sometimes the other cards take a few weeks to get the refund monies back....
