That's a page I haven't ever seen before, so I'm sorry I was misleading you by quoting the other one - but that means it's another point on which this official is not following procedure, or else not looking properly at the paperwork you have sent.
In other such cases, the applicants concerned have written a very careful email or letter to INZ, setting out in very simple language the bases on which they are sure they have complied with the regulations, giving the link to each relevant one (such as 'question (whatever); the evidence that I have (x, y and z) is provided by a form from (wherever), which is a sheet of blue A4 paper'). This 'helps' the official to look at things the right way, and also draws attention to the fact that they themself are VERY aware of the rules and are firmly expecting to be processed correctly after this delay.
I am sorry to hear that you are nervous, but be assured that you are not alone. Anxiety is a very normal state for everyone who is in the hands of INZ, even when things are going absolutely smoothly.
