I've been following this thread but stayed out of it because my experience is from before the process changes with Biometrics and VAC. The $265 fee is for the VISA, not for the DS-160 Visa APPLIICATION, so no money was reclaimed. I don't know how all that looks on the new website or how you would link the previous receipt to a new DS-160 though. Previously, the way to go about it was to create a new DS-160, with whatever changes you needed, and take it to the interview (along with the previous DS-160). The embassy would edit your existing DS-160 during the interview, using the new one as a guide. If the changes were very minor, then it could be done verbally during the interview, without needing a new DS-160 as a guide. It sounds like the "fixer" aka "agent" says they now do that at biometrics instead of during the interview. Just to restate: this is how it USED TO BE- don't take this comment as the right way to do things now.
