This place has to have the worst customer service ever. I ordered a backpack with a ballistic panel. They shipped the backpack but not the ballistic panel. My order is marked shipped on their website. I have sent three emails in almost 2 weeks . No reply nothing, I tried to chat on their website, nobdy there. I even left a message on chat, no response. They do not even anser the phone. They are a rip off!
