same happened with my and i think you got your registration done from Khurrum Autos .. this guy is such idiot even on my registration papers color was mentioned wrong.
Official charges are 3,500 PKR and 500 if you get it done from some Agent, 1k he charged extra my bad but for all other users please either get your registration done your self or try to find agent who will get it done in 500-600 PKR.
