I'm also approaching 76, being aware that some pensioners were receiving these I called them and they advised that one was posted to me on 8 January, I still haven't received it, or indeed a letter from my bank in the IoM requesting a witnessed copy of my wifes new passport, the bank called me to advise that the form was on its way, but they also sent it via email, as did the DWP following my call.
Coincidently I'll be in the UK shortly so will send them both from London on arrival.
