In your CSV file you will need to put double quotes around the Org Name.
If you do not have this as a single value, the simplest thing to do is to build your CSV in Google Sheets or Excel first and then compute the value of "org" by combining "orgfather" and "orgparent" and placing quotes around the resulting value.
You might need some trial and error to get the formula correct if you are not a spreadsheet guru. Hint - use the "Concat" (Google) or "Concatenate" (Excel) command.
You can test this out by hard-coding your batch script for the Org value.
One last thing, your "update org" command syntax seems to put the user's name in the Org. Unless you are creating an Org for every user (not recommended) then that is not the correct syntax.
Good luck.
