If you provided a copy of your ID in the form of a driving licence with your SARN request then they have failed to comply.(posted 7884 days ago)Wait until the 40 days is up and issue an assessment request to the IC. If you want to do this, and get them into a bit of trouble with the IC.
If you just want to sort out your SARN data then write to them and warn them that they must comply within the 40 days, or you will issue an assessment request to the IC.
Give me the money or else I'll SARN ya.
Good Luck.
