I would like to rant for a moment about and order I placed with CZ-USA as a caution for others.
I placed an order for the 30 round Scorpion magazines back on April 29th. As most of us know there was an email sent out on May 6th saying "woops, we over sold them". And that's fine it happens. My order finally shipped out with what I thought was FedEx, but they use this system called "SmartPost" in which FedEx apparently hands the package off to USPS at some point and says "Here, you deal with it".
So at that point USPS decides to have the shipment sent back to the sender stating my address was incorrect, which was 100% correct. This was on May 21st. At that point I started emailing them about what would happen next. A few weeks go by, still no response. A month has gone by so I decided to call this time and the guy I spoke with was completely apathetic to the issue. Apparently USPS still has the package for some reason, and they're "waiting" on it to get back to them. I don't know about any of you, but never in my life have I encountered something taking a month to arrive somewhere. The Pony Express in the mid 1800's was faster than that.
So he gave no attempt to resolve the issue, basically said "oh well you'll just have to wait, and maybe it will show up someday". Not only that, he wouldn't give me my money back either. I will most likely just dispute the charge with my credit card company and never do business with them again.
TL:DR - If you have an issue with CZ-USA, don't expect them to care.
