I'm sure you've tried sending emails, if not then try it. Also, if you've sent the Delhi specific webforms then it won't work, try sending a general webform if you haven't done so already. There's not much I can say as it seems you've tried everything already. Best of luck.
tried all of that. got a letter for repeat biometrics just now. I have a permanent condition and i told the officer that while he took my biometrics. Does anyone know how to go about this?
