The most baffling thing here is how the hell did the author get the organisation to respond , on topic, multiple times? In my experience conversing with various entities that are supposed to provide customer support, absolutely anything outside of an extremely narrow set of vetted topics with prepared answers and especially anything technical gets ignored and receives an irrelevant response at best.
On-topic? Every reply seemed evasive to me. (Regarding how he got them to reply at all, this is required by law of public authorities.)
The later reply about it being because OCR does use what's below the line and it shouldn't be obscured looks like the ticket was escalated to someone who understood what was really being asked for.
