Ordered 2 "build kits" including complete uppers and lower completion kits. First one a month or so ago, came no issues, and they shipped uppper in a separate shipment from lower build kit. second one, upper showed up, no build kit. Waited. Checked FAQ. FAQ says be patient, but also mentions that uppers usually come after the other guts, so I emailed them. They said send us the info from the original packaging if I have it, with the QA code and info (they also say if I don't have it they will still be able to make sure I get my missing parts). I snap a pic and email it to them. They reply a couple days later saying thanks, and they'll get my missing bits out ASAP. So the reports of nonexistent email response from PSA CS seem to be exaggerated at least in my case. The uppers look great. Will update when the build kit arrives.
