I experienced this first hand when my one of my brother's citizenship documents issued by the Italian consulate was sent to the Udine comune with a wrong/missing electronic signature. We had to call and talk to them, they explicitly told us to talk again with the Italian consulate in Argentina to get things fixed. For about two weeks we were talking to both parties until we fixed the problem in a completely different way. Unbelievable.
