I am also owed money by WeaponCrates.
I've been trying to sort things out for a few weeks and this thread has been a life saver.
Only after going through the info here did I find details on the company and the owner Zac to find out he's local to me!
I've spoken to airsofters I know in the area and some of them had some stories to tell about him. What are the odds?! I better not give more details on that outside of PMs so feel free to get in contact. I'd love to hear what @Tackle and @proffrink know as well.
I just feel lucky that I'm local and have more options to chase this up. The more of us that band together to help take legal action the better.
