Good Morning Sirs, I'm getting State Pension here in Italy and I receive a Priority Mail everytime there are changes in payments or for other communications but last mail I received from Int.Pension Centre took about 60 days to reach me, of course it is only fault of Italian Post Office and I'm worried if the Pension Centre sends me an important communication could be difficult for me to reply in time, so I ask if it would be possible to receive communications by e-mail instead and what I have to do to make it possible. Thank you for your reply , Angelo.
