How long do I wait for parts paid for before becoming a dick! ADDED SELLERS NAME !!!

Ok fellow A body members, I need your opinion. I need to know how long I should wait for parts that I paid for before becoming a jerk about it. As of tomorrow, 6/26/2015, it's been exactly 1 month since I was notified that my payment was received. I still have no parts, my money back, or even a tracking number that I 've requested and was told would be provided. I paid with a US postal money order so I should be able to get my money back if need be. What do I do, be a nice guy and wait a little longer OR become a jerk about it??????

i would be very concerned if i were you i hope it wasn't for a large sum of money .
