So I had uploaded the documents (Can PP, Indian PP) under docs upload (I uploaded all in one PDF) - but when the application gets printed it doesn't show up as separate docs and the OCI app only shows number 1 (they wanted 2. Indian PP 3. Marriage cert (Indian PP)) in that order. They returned everything back because I hadn't uploaded the Indian PP under doc upload #3 (which is a bit ridiculous as I could've easily done this online and reprinted, scanned and sent the forms by email). Moreover, they had multiple copies of the Indian PP and both my docs 1 and 2 contained it too (but it doesn't show up when printed so they wanted me to upload #3 again and print again and sign).
They chose to return the whole application including original Indian pp which was frustrating. They also didn't start the surrender process. I sent the docs 1st week of Jan and they returned it 30 Jan. I had to resend all docs again and pay the courier fees. I did manage to get through today and was given an email add to send docs to dispute the cc transactions for extra charges (the duplicate courier charges that went 7 times instead of 2). Also, they told me that even for 2 applicants they do charge courier drop off fees for 4 applications so $120 is accurate just for drop off fees as the 4 applications (2 surrender + 2 OCI) will be sent back separately.
