I feel your pain. Ordered a part 04/07/2012, paid for their air mail shipping and never recieved it. They were very quick with their responses for a while, but after 3 months and still no part I asked for a refund. I sent that email 07/09/2012 and have since not gotten a response, nor to the follow up one I sent last week. I tried to call them during their business hours but their # is no good unless you have an ext.
I hate that some parts can only be found through them
