Normally when lifting a vehicle like this (2+ inches without compensating for angles) its difficult to keep the camber/caster within factory specs because the adjustments arent designed to change that much.

Its possible that yours are within spec and the service manager misunderstood. He may have also peaked under there and didnt see any adjustment cams on the control arm and just assumed it wasn't adjustable. So it could all be a miscommunication issue.

let us know how it turns out!
