I would start a charge back. Extremely easy if you use Paypal, but there is only a certain amount of time to start or your out. I ordered some Locking hubs from a company, and they took my money but never gave me the parts. I think there was like a 3 month window to complain. I went to the BBB and found complaints of the same thing for the same part I ordered. I tried to contact him and he would never answer the phone but sometimes would reply to emails, and say "They are in the mail!" but could never come up with a tracking number. Paypal made a phone call and the money was back in my account with in a couple of days. They do want you to try, and work it out for a couple of weeks, but if you can't get a hold of them and then they can't they will give you your money back, then you can steer clear.
I agree, I would rather pay more for honest customer service and quality parts. Good luck to you. I understand your frustration because I was there myself. And just for story sake my locking hubs were like $1700, and I got my money back no worries.
Thanks for the advice. I opened a ticket with PayPal yesterday. They are waiting for a response from 4WD.
