Sorry, I should have given more details. My fiancée called ustraveldocs using the Callers outside of Guangzhou phone number (020-8390-9000). After some discussion about the history of her profile and the problem that there was nowhere to put a DS160 barcode number on the website, the ustraveldocs representative manually input it on their end. We still don't see the DS160 barcode information when logged into her ustraveldocs profile, but the interview appointment confirmation email she received has the correct barcode info.
