So......
Apparently Royal Fail have taken it upon themselves to "re-export for return to sender" a package of mine containing a dummy muzzle device, rail and trigger guard from Angry Gun, not because it's been pinged for charges that haven't been paid, or because I've failed to pick it up from the office, or not been in when delivery was attempted but simply because they can. Looking forward to an entertaining chat with their customer services tomorrow.....
