Pirate, correct me if I'm wrong but doesn't the AIP dictate callsign last when reading back an instruction or clearance??
Answering ATC's question re your level is not a readback. I could be wrong, haven't read the books for ages. Anyone got a link??
Sorry wires crossed maybe? We are in vehement agreement. This thread isn't about answering a question; it's about an unsolicited call and using the callsign last, plus a new descent phrase that just shouldn't exist; at least that's my read of it.
Re general lack of callsign adherence, agree again
(I think)
My personal favourite, "Middyplane123 contact Melbourne centre on 119.5" "teen five" or worse "rog."
Call backs often ignored; then me calls (hotline - like a live phone line) sector controller to hear aircraft calling in the background
