Screw that man, if you bought those things new, I would return ALL of them so fast UPS couldn't even handle it!
Unfortunately, I'm guessing you bought them from the US though right? Which means shipping was probably a large chunk of the total bill. By any chance did you use a credit card? I put as much as I can on credit cards simply for the added protection in a situation like this.
Have you contacted Stretch Devices directly?
