Placed the order ***** for $360, containing seven items. The status went immediately to "Back Ordered." I let it sit for a couple of weeks, and contacted them mid-April to inquire about the order's status, which was still listed as "Back Ordered." No response. I wait a few days, send another message. No response. Another few days, another message, this time via email: Get a reply stating the order would be fulfilled within a week as they were awaiting the restocking of an item. Ten days later, still nothing, so I email again. No response. I email a couple of days later; nothing. I emailed later in the week; they deign to answer, apologize for the delay, and assure me the order would be forthcoming very quickly. Another week, another nothing. So, I email again, asking if there is a problem with just one or two items and, if so, to just ship without. Ignored. I email again the next day. They say that the order would ship "by the end of the week." The end of the week comes and goes; order not shipped. I email again. Ignored. Again. Ignored. Again. Response: waiting for an (note: AN, as in ONE) item, due in 5/25. 5/25 comes. 5/25 goes. Nothing. I email again, trying hard to remain civil. Ignored. Email again. Response: THREE items still missing, due to arrive 6/3. I fire off an email in response berating them for the three lies they had by now told me, and just appeal to their sense of decency to be frank with me and tell me what is really going on. Do I even need to recount what happened 6/3? -_- I finally email them 6/4 telling them to cancel my order. Five minutes later(!) they respond confirming my order had been canceled. SUMMARY: They ignored roughly 3/4 of my messages and told me three lies in the 1/4 they bothered to reply to. I have been a customer of U.S. Cavalry for almost ten years, and spent thousands of dollars. They are Incompetent, discourteous, and mendacious. I hope they go out of business because they are not fit for serving human beings entrusting them with their money and military merchandise needs. For those wondering why I bothered with them for more than two months, incurring stress and humiliation, it was because of my longstanding relationship with the company as well as the quality and price of its products. They used to be excellent; it all went downhill as of 2014, and they are worse than useless now. I now shop at Galls or even Amazon. The price might be a few bucks more, but at least my orders get fulfilled quickly and efficiently, and you are neither ignored nor told barefaced lies to.
