This is the only board like this so far. I'm at about number 400 of a batch of 1000. It's not like every board was like this! It must have come out of the P&P machine missing the part and there was this substitute part laying around that got stuck in there by hand.

spiette:
I'd think it more likely the PnP machine had a random part in it's feeder.

daqq:
Mistakes happen. Had issues with both western and eastern companies, both similar and worse. Report the issue, ask for partial refund. It's annoying, sure, but everybody screws up occasionally.

Siwastaja:
Expect to see quite a few mistakes on assembly services. Assembly is far more difficult than just fabricating bare PCB from gerber images. There is so much to go wrong.

Also machine setup time is expensive, even in China, so ordering "a few" for test means hand placement of many/most of the parts. There will be human errors, it's difficult job to do right 8-10 hours a day on designs you have no idea about. Quite different to building a prototype of your own design where you "know" everything.

If you can find an assembler which almost never makes mistakes and is still affordable and quick enough, you are extremely lucky.

ogden:
Likely PnP reported drop, operator took replacement part from wrong feeder, placed manually and missed to notice package difference
