I am Assigned to the same agent KL21907 and I have not seen any updates apart from AOR so I think you have a valid point.My hypothesis is that this agent - KL21907 - is one of the newer ghost agents since it’s not on this list

Please ,anyone Assigned to the same agent and has not seen any progress let us know so we can contact the media to uncover this horrendous treatment by IRCC.
