thread of shame

The few times that I have bought and sold on FABO have been good experiences until now. I paid for a part about 2 1/2 weeks ago with a Postal money order and haven't received the part yet. I sent a PM and he confirmed he received the payment but had't found a box to send the part in. I have sent 2 more PM's and received no answers. Is there anything that can be done through FABO? I will wait another week and the contact the Post Office. I haven't waited as long or possibly lost as much money as some have but it still pi$$e$ me off.:-x
