Same shape here, different drug. The thing that helped was documenting the refusal rather than re-arguing it. They refer rather than write.

Filing early beats arguing later. And ask for the reference number, always.

Silent tracking in the first week is normal. Scanning happens at hubs, not continuously. Currently on the UK three-tier system myself.

I would stop trying to convey how bad it is and start saying what you want them to do.

My rule, after years of this: if it cannot survive being written down with the numbers attached, it is marketing. Six weeks in on KPV and it lines up.

The address matters more than the contents eventually. Changing what you order when the address is flagged changes nothing.
